My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.

2002 Ford Ranger edge 3.0 flex ... Truck was running fine and giving me no issues. I woke for work the other day and went to get coffee and truck wouldnt start. I could hear fuel pump running and knew it wasnt that, it was acting flooded. So today I pulled fuse from fuel pump relay, and got it to start. Put the fuse back in and ran to gas station. On the way to the gas station it started running really rough, very low and rough idle, trying to stall out. I noticed it had black smoke coming from exhaust. I got it home, and got it to start barely, and it has the same very low and rough idle, but my oil gauge was going crazy, flickering back and forth all crazy, and the idol is terribly rough and eventually stalls out. Earlier today I did put new spark plugs in it, but not sure that has anything to do with the issue. I also hooked it up to a computer and it isnt throwing any codes.

The problem only occurs on a cold start. I put the key in and start the motor. It starts fine. It runs fine for about three(3) seconds and then the RPM's start to dive (I have to give it gas to keep it from dying). The exhaust begins to put out quite a bit of smoke and the engine runs really really really rough,... kinda like it has a heavy cam in it.
After a few minutes of this exhaust smoke and rough running, the engine of course is warming up. The RPM's start to come up on its own, the exhaust smoke disappears and the really really really rough idle (not really an idle because I have to give it gas to prevent the motor from dying) disappears and the car idles perfectly.This cold start problem also uses up a noticeable amount of gasoline.

I'm losing coolant have, excessive white smoke coming from the exhaust, and rough idle. Doesn't over heat or even try to overheat. The oil fill cap looks brownish white. It drives fine other than extremely rough idle. I know how to check a blown head gasket with the combustion gas test.
From what I've read blown head gaskets on 4.6 fords are fairly uncommon but a blown intake gasket is fairly common. How can I tell the difference?

I have a 2004 Excursion with a 6.0 Bought the truck already studded, EGR deleted, and a 54V FICM. When I bought the truck it had a hot stall, no restart problem. Found the high pressure oil leaks and resealed them by replacing the #3 injector and replacing the top injector seal in the #4 .Oil pressure reads very good now and I drove the truck for a couple weeks problem free.
Truck started smoking (white to gray) and felt like it had a miss. No misfire or contribution codes. Truck failed the bubble test and I narrowed the leak down to the passenger side by removing the banjo bolt
Banjo bolt at the front of the passenger head
Found the #3 injector loose...the copper washer
Copper washer had disintegrated/melted and appeared to be stuck to the side of the injector. Scraped off easily enough, cleaned up the injector and injector cup and reinstalled the injector with new O-rings and copper washer.
Put the truck back together and still smoked the same and still felt like it had a miss. Ran KOER test and found sometimes a contribution code for #2 and sometimes #6 .
Drove the truck to work and it didn't feel down on power...mostly just smoked and rough idle...but on the way home there was a lack of power and just as I pulled into my driveway the truck stalled...wouldn't restart. FICM voltage was good, high pressure oil read over 900, IPR was holding around 40%.
Pulled the secondary fuel cap
Secondary fuel cap to run another bubble test...there was no fuel in it...completely empty. Started to think that I had a fuel feed problem. Hooked up a fuel pressure gauge
Fuel pressure gauge and drove the truck again...pressure wasn't great (45 lbs) but never dropped below 42...not even when it stalled. Pulled the cap again...dry again...yet the truck read fuel pressure.
Research showed that I was possibly pressurizing the fuel system with combustion pressure and that was possibly displacing the fuel from the fuel system. This would explain the run for a few minutes, then stall and no restart for a few minutes...I'm assuming that the pressure would bleed off and the fuel pump would start over.
Still failing the bubble test and still pointing to the passenger side. I pulled and recleaned the injector and cup...new orings
oRings and copper washer. Bubble test again...fail.
Pulled glow plug from #3 , failed bubble test still.
Pulled glow plug from #1 , failed.
Pulled #5 , failed...pulled #7 ...failed.
With no glow plugs in the passenger head I am still bubbling up to the fuel filter housing. Pulled the banjo bolt from the front of the drivers side head...no more bubbles.

I have an 02 Venture WB Package with the 3400 engine. Within the last week is has started to run rough under load. This happens mainly when it is driving, but it does happen at idle when there is an incline or decline.
A little background of what happened. It has not wanted to start all of the time and i heard that it might be a dirty MAF. Well, the MAF is clean and still not wanted to start all or the time. During this time I noticed a plastic line going from the intake tube into the rear valve cover was loose, so I thought this was the problem. I have big hands and couldn't reach the rear vavle cover without rocking the engine forward. When I finally got the bolts out of the mounts that attache to the engine, the engine rocked back a little. I didn't think anything of this and ratchet strapped the engine forward so i could reach the valve cover.
I got the line back in and put the engine back where it is supposed to go and all was well. A few days after doing this my wife told me the van was running rough so i took it for a spin and she was correct. It is hard to describe the sound it makes, but it almost sounds like there is was too much stress on the engine when I have the gas peddle pressed. The van doesn't lose any power i don't think. The van sounds great if it is coasting.
It only does this when there is a load on the engine in drive or if it is idle or parked on an incline or decline. It goes into the shop on thursday the 30th, but I would rather not spend the cash if i can do it myself. I am totally lost with this one. I have a video of the sound when I am driving it, but the sound isn't too loud on the video.

This is my uncles car and Im doing this for him. Its a 2003 Venture that he has had since new. It overheated but there is no water in the oil and there is water in the radiator so I'm thinking that the thermostat froze not allowing water to circulate. It runs rough, makes a bit of noise from the top end.

Truck started running rough on way home the other day. First gave me P0404 code and would get black smoke along with whitish smoke coming from the tail pipe. I haven't been able to notice or track an amount of coolant loss yet.
Swapped EGR valve this morning and now noticed this once she kicked into high idle (still warming up). About to hook up the IDS, hoping I this is not head gasket .

I just looked back and it has been since July 7th that my girl has been sitting in my shop. Well this past weekend I finally got her back together and started. It took a while to build pressure but she finally came to life..
While I am thrilled that she is running again i have low power before the boost kicks in and is idling rough with a blueish- white smoke coming out of the exhaust. Once i kick her a little she will get up and go but I've never had the smoke before.
I'm thinking maybe a bad injector???

I just purchased a 2003 V10 with 270 000kms. The truck had had regular maintenance. It has an exhaust leak and runs a little bit rough. Could the exhaust leak cause the truck to run a little rough or am I dealing with another issue?

I have a 1985 Silverado where a mouse must have chewed through the main electrical wire that goes from the battery to the starter. Without knowing this, I tried to start the truck, it turned over a couple times, then a burnt electrical smell and smoke was coming from under the hood.
I replaced the wire and the starter. Now I have all electronics restored but when I turn the key, nothing happens. The lights don't dim and it doesn't even click. If I arc the solenoid on the starter, it turns over and runs just fine.
I have checked all the fuses and relays under the dash. Those don't appear burnt out and I've tried swapping relays and that doesn't work either.
Is there anything else that could have shorted out? Are there other fuses or relays that I'm missing? Or is there something with the ignition that could be causing it?

My van ran fine, no problems until yesterday. I started it and it ran for a few minutes then I heard it bog down 2 times ran for a few more minutes fine then stalled. Now it turns over but will not start. I can hear fuel pump, I changed fuel filter.

My Venture LS is stumbling upon acceleration. It starts to occur around 35 mph and then continues with occasional smooth sailing. No rough idle and no stumble when coasting. I had the spark plugs and wires replaced at the dealer today and it did nothing. Fuel trim is fine, LT runs from 0 to - 5 . I replaced the MAF sensor a few months ago and all other sensors test OK on the scanner.
Also, I took my car to the dealership to have the plugs and wires replaced and they used the after market wires named Xact. I have never been to a dealer where they used aftermarket parts. I thought that they were required by GM to use their parts?

Where the EGR Valve is located on a 2001 Chevy Venture? Pics of its location would be nice, if possible...

Yesterday our 2002 Chevy Venture minivan died in the store's parking lot. It would not stay running when we started it and let off the gas. As long as we were pushing the gas pedal down, the van would run. As soon as you let off the gas, it died.
So my husband walked to the auto store and bought a new fuel filter. He then tried to replace it in the store parking lot. As soon as he took off the 'male hose' from the fuel filter, a lot of gasoline sprayed him in his face and of course he came out from under the van screaming and in pain. (Don't worry with kids we had over 8 bottles of water in the van and I flushed his face and eyes for over 10 min and he is fine now).
Anyway, in the process of flailing under the van when the gas hit his face, he jumbled up these little black and rainbow colored rings and lost a long rusty screw/bolt that screws the main round body of the fuel filter to the underneath of the car and holds it in place.
We searched and could not find the bolt. My husband jumbled up the small rubber rings and did not know what was from the old or new filter. He tried placing them on the new fuel filter but as soon as he turned on the car, not even the engine just turned the key to where you can play the radio... all this gas sprayed out from the new fuel filter. After many tries of re-arranging the little o rings he gave up and called a tow truck.
Today he called auto zone and they looked at a new fuel filter in it's box (same one my husband bought) and told my husband that there was only one small black o ring on the fuel filter. So he put one ring on his new fuel filter (on the male hose I think) but still the filter sprays gas as soon as he turns the key. He then went and bought new 'hose clips' and tried those. The fuel filter still sprayed gas.
So, what I am now trying to find out is what could possibly be causing the fuel filter to spray the gas (leak). My husband (in his words) is a welder, not a modern car mechanic and is getting really stressed over this.
1. Does he need new or different sized little rubber rings?
2. Could the missing bolt that screws the large body of the filter to the car be causing this gas leak?
3. I read he should turn off the gas some where and then replace the filter, could this cause a gad leak issue because he did not do this before replacing the fuel filter?

I have checked the fuses and they are all good. I turn on the headlights and the dash lights do come on at that point but I have no power to the buttons on the panel or any of the climate settings.

Got done with replacing head gaskets and intake gaskets, Van started fine and I backed it out of the garage. Left it running and put down ramps and drove up on them so I could get under and connect the exhaust. Got that done and then got back in it and all it will do is crank and it will not start now. It also has a new cam shaft sensor( wire broke on old one). I can hear the fuel pump when I turn the key. It is like now there is no fire to start it. What could be wrong? What do I check? What causes it to fire? If something was connected wrong, would it have still started and then wont do anything but crank? Got dark on me and started raining so I say tomorrow is another day. I feel it is something simple.

The 1999 Chevy Venture I have doesn't get enough power from the motor and lacks the force to accelerate, was told it could be with the sensors? Which sensors and where could they be located?

I picked up this 2004 Chevy Venture for my daughter and it has a power steering fluid leak coming out of the power steering cooler line that runs along the frame in front. I know that the procedure to replace this line calls for disconnecting the intermediate shaft of the steering and lowering the subframe to gain access to the line connections on the rack. My question is, is it possible to replace that line without lowering the subframe? I ordered the new line and it's on its way. I wanna do the job right.
