Intrepid :: 95 3.3L Choke Out / Can't Accelerate
Nov 22, 2010
I can usually get up to 25mph no problem but above that and the car acts like it wants to choke out, then it doesn't want to shift gears (example the other day on a slight down hill grade and only because it was a down hill grade I got up to 50mph running around 4300rpms it wouldn't shift ). If I accelerate slowly some times it will shift then with out notice it will down shift (hard).
While in park or neutral when i step on the gas and hold it will rev up to 4000rpms then start to bog down or cut out dropping down to less then 3000rpms before i take my foot off. While the rpm's are dropping it sounds like it is starting to back fire.
There was a mil code for the fuel injectors but has not come back since i cleared it. I have change the transmission fluid and filter and replaced the crankshaft sensor.

I've got a 95 Intrepid that wont seem to change gears when I have the accelerator all the way down (from standing and passing gear). Other than that it seems ok. I want to add some Lucas. I am worried about overfilling...Lucas says a moderate overfill is ok, but I am still apprehensive.

Ok, so every now and then when I turn my car on it will feel as though it's not getting enough power, and will make a sound like "prum prum prum prum", and then if I touch the gas it will choke and shut off. If I try starting it again it won't even start, I'd have to wait 3-8 minutes or so and try starting it and when it does start, I give it some gas, rev it to maybe 3-4k rpm, and it will be A-OK and drive with no problems. Now this doesnt happen every day. I may use my car 4-6 times in one day and it will start no problem. The next day I try using it, it will do "its thing" and will not start.
Now, when it does "its thing" my ESP light or traction control light goes off and the light stays until I start it again but even if I try turning it off with the ESP switch it doesn't work. I'm guessing the problem could be either the fuel pump, fuel filter, or alternator but I'm not exactly a mechanic, nor do I know a load about cars either.
Finally got the codes all 9 of them :
p0491
p0492
p2401
p0057
p0037
p0031
p0051
p0141
p0161

Engine runs fine while in park but if put into drive rpm's won't get above 2500 then begins to choke.
-Fuel filter changed
-no vacuum leaks
-disconnected cat
-good spark

Have a Accent GLS 1.6L, 92,000 miles on it the issue is what I stated above.
Basically back in March I started having issues with my car and it seemed like it was misfiring or something of the sorts at first I thought it was the IAC motor because it would only intermittently kind of "choke" if you will and it only did it while I was idling and in drive. So before I decided to go further with the IAC motor I decided to take it and have the throttle body cleaned, but it eventually started to do it again. After that I had my fuel injectors cleaned and that didn't work much at all. Kept going until a couple months ago when it actually set off a check engine light and it started doing it almost violently.
Check engine light came up with the result that coil 2 is misfiring and I went about replacing the spark plugs and the boot to one of the coils and that made the issue go away no check engine light, no nothing. Past couple days it's been doing it very very occasionally but yet still doing it.
I don't have a whole lot of cash but I need a solution quickly because this is starting to become a pain I don't want it to become so bad that I'm without a vehicle that is operating properly again.
Only thing I can note is that now it is very occasional, and when the car could be otherwise be considered "cold" and often I can't make it repeat the same thing. Had oil above cylinders when I had the plugs replaced.

The choke is never setting. Something in my throttle linkage is wrong or sticky and it doesn't flip up the lever that engages the choke?
Hard to explain. Hopefully, the video makes it clear?

The gasket blew out on the choke (tube) plate on my 460. The one that sits on the engine with the tubes running up to the choke.
Do I need to apply a gasket sealer when I replace it or does it just go on dry? I've read some conflicting opinions on it. A tad on the corners to hold it in place. Put it on dry or put sealer on it.
I know when I remove it I will be able to tell but since I don't have any hi temp sealant. I'd rather buy some when I get the gasket than go back.

While the car is at a full stop it idles at 500 rpm. I am assuming this is normal. But randomly the accelerator dips and the entire car jerks and feels like the engine is going to choke.
This started happening when the vehicle was at 10K miles and I took it to the dealer but the problem did not repeat itself there. They said they ran all sorts of diagnostics and came up with nothing. At this time the problem would occur may be a few times a week, while waiting at a red light, etc.
Now the vehicle is a 30K miles and it is happening more frequently. Several times a day.
I recorded a video of it to better explain the problem.

1979 ford f-150, 460 w/ 4bbl. Carb recently rebuilt by professional, but on cold mornings (in particular) runs rough even after a little warm (just like me), like the choke isn't clicked or clacked (couldn't resist) off. Can the choke flap and mechanism be gunked up, needs some cleaner applied?

I have a newly remanufactured Holley 1835 carb which has had an electric choke added to it. My '59 F-100 has the original electrical system in place. Where would you recommend running the positive and negative wires from the choke? No instructions came with the carb.

I've got a '84 ranger that idles super fast for about 30 minutes after a cold start. The truck has been in the family since new and has done it since day one. I am wondering if replacing the electric choke or choke pull down would work. I've got a electric choke replacement but the cover place looks to be attached with rivets not screws. How to remove the choke?

So I picked up a 2 barrel carburetor of a 1972 Ford Truck, most likely an F250. Has a tag and everything, this is a Motorcraft 2100-D (D2TF JB). No electric choke or anything like that. So I'm wondering if I can run the carb with choke permanently open? Also is there an electric choke conversion that I can buy, if so where is it? I can't seem to find one. Also what are the adjustments? I seem to have 2 needle valves to adjust and one other.

My truck is a 1995 Explorer 4.0 150,000 miles, 5 speed.
Problem - Rough idle : when cold it's worse and will stall and choke a little. When warmed up it just has a rough idle but will not stall and stays at a pretty constant RPM. It's very tolerable when warmed up but still not right. It drives fine once off idle. No black smoke that I can see. Power may be just a little off but I would not bet on it. MPG seems about normal but haven't been on a long enough trip since problem started to tell for sure. Also longer than normal cranking on occasion.
Diagnostics so far : Fuel pressure is at 32 PSI, vacuum off regulator it's at 40 PSI. Not sure about key on only as I don't trust the autozone loaner gauges. You have to fiddle with it each time before it will read. Leak down after 30 minutes was about 4 PSI
No Check engine light ever. KOEO test shows no hard or on demand codes, I get the 111 pass. From CM I get 336 and 45.
336 is EGR related and my looks pretty rusty. I put a vacuum pump on it while running and the EGR held vacuum but had no effect at all on idle, I was expecting it to get worse as I opened the EGR so it may be stuck.
Searched high and low for vacuum leaks by ear, visual and with starting fluid all turned up nothing.
Actions so far : Replaced plugs, wires, IAC, and fuel filter. Cleaned MAF sensor and throttle body plus ran lucas fuel injector cleaner through it.
Next steps : I've got the EGR but it's so rusty I am sure I'll break the tube it bolts to plus I don't know it that alone will cause the rough idle. Will the DPFE sensor and/or EVR create a rough idle yet not turn on the CEL?
Thought about changing the fuel pump and/or regulator but the numbers are not terrible. Agree?
Thought about changing the intake gaskets but don't see any leaks.

I picked up a renamed 2100 for my '72 and I found out choke vacuum control on the back of the carb is frozen. Are these parts still produced and if not is there another way to make it work?

My car has been having a cool start acceleration problem in the past couple weeks.
After I start the engine, switch to D ("Drive"), and step on the gas paddle half way, the car will go forward for about 1 feet. Then it will choke for couple seconds. If I release the gas paddle and then step on it again, it will do the same thing.
However, if I just slightly step on it and let it slowly accelerate, it will be fine. Also, it only happens on a cold start.

while scraping ice off the windshield this morning with the car warming up, it started to choke, engine light came on. Used my OBD reader and found only one code, that being p0740. Cleared the code and all was fine after that, it drives the same way it always has and nothing feels different, revs are the same shifts gears the same. I know it had something to do with the torque converter clutch.

So my story starts simple enough; I ran out of gas in my buddy's car, filled it back up, it finally started but ran like >poop< for the first 10 min or so. Finally after coaxing for 10-15 min, she stays coming around. After 30 min or so of driving, I could drive her all I wanted, so long as I didn't let it idle below 12-1500 rpm. If I did that, she'd kill, and stall out. Well I drove her the other day for most the day and it seemed the kinks were worked out. So today when I tried to drive her round the block for a final check, she up and dies, and hasn't started since. I've replaced the fuel filter, checked the intake, and dropped a can of sea foam in to the tank to boot, but no dice.Signs and symptoms seem to mimic a bad mass air flow sensor or possibly a clogged catalytic converter, with the exception that it only shudders and acts congested on low rpm's and doesn't choke out at high revs.

I bought a new Holley 600 CFM 4150 with electric choke for my 79 ford F 250 with 400 engine. If I start the truck cold the choke works as it should and after driving 10 or so minutes it runs fine off choke. When I restart the truck after stopping for gas or food it goes back on high idle even with the engine temp at 180 degrees. Should it go on high idle even on a hot day fully warmed up every time i start it? I don't remember my last 600 doing it.

I have a 98 Grand Cherokee (V-8) with 127K on it, that sometimes during cold starts acts like an old carburetor system with the choke sticking. It floods, chokes, it sputters, and you have to maintain an RPM of about 2000 to keep it running and get it to snap out of it. A local shop did a tune up on it before this problem started to happen intermittently, aside from this, it seems to run well. I took it back to the shop and they did several diagnostic tests and even got it to do it for them while they had it.
I told them that it seemed like if we released the key from the start position as soon as it began to fire, the problem would happen, if we held it I the start for a bit longer we could usually avoid it. They returned it to me saying that "Yup, if you hold the start position longer it won't happen, and by the way here is a bill for $103." With the recent below zero temps, it's getting worse, almost unavoidable. My wife says it uses a lot of fuel when this is happening but we have not actually tracked the mileage. Other than this it's a great car but I'm ready to drive it off a high mountain cliff.

I have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.

I picked up a remaned 2100 for my '72 and I found out choke vacuum control on the back of the carb is frozen. I can't find anyone who carries it, let alone knows what it is. Are these parts still produced and if not is there another way to make it work?
