TrailBlazer :: Ways To Test Coil Packs?
Dec 2, 2013
2004 TB EXT, 4.2L I-6. Steady misfire on a single cyl. Changed spark plugs, (installed A/C Delco Iridium, 41-103). Fired it up, and miss was gone for about 20 seconds, then came back. Scan turned up P0301, Cyl #1 misfire. I picked up a coil pack, but before installing it, is there any diagnostic tests I can do on the connector, or any tester for coil packs? Not wanting to install this $80 part, (rendering it non-returnable), and have it make no difference. Hoping to at least be able to check for proper voltage supply and trigger signal at coil connector, if possible. Also, any checks I can perform on the injector harness? Thinking it may be one or the other. Or should I swap coil pack to another cylinder, and see if problem moves with it?

I am trying to get my spark plugs changed and having a hard time trying to figure out how to get the coil packs out. I have done some research already but couldn't really find anything solid for the GS 460 specifically. Many people had useful information on the other GS models (300,350 etc) but since the 460 is not as common, I couldn't really find anything.
I read the guys use pry bars to wedge the motor a little to have extra clearance to pull the coil packs out but it seems the LS has a little more room to work with. On the GS 460 however, it is pretty tight and even using a pry bar I really do not believe the coil pack will have room to be remove completely.

Having issues with some or all of the coil packs going bad? Because it looks like all 6 coil packs on my R32 went bad...
Brief history, my car stopped turning on about a month ago, it was working just fine when one day when going to lunch it stopped wanting to turn on, I had to crank it about 3 or 4 times and it turned on, I went to lunch then got back but when I left for the day (at work) I once again didn't want to turn on and that's about it. I had to tow it home and a couple of friends and I began trying to figure out why we tested the fuel system and electrical. We could get no little to no spark on all 6 coil packs. Ran vag com and nothing would come up, I tested the Crank position sensor and it tested fine but broke the connector so I replaced it with a new CPS. Still, would not start.
So after a couple of days, we decided to try 6 known good coil packs and it fired right up. So yeah I've never heard of all six coil packs going bad at the same time, so what could cause that ? btw soon after the car started, about the 3rd time turning it off and on the starter decided to stop working, I'm thinking it was because of all the times I tried to start it, it was allotted. : thumb down

I've decided to jump on the DIY bandwagon a do my own 60K service. I've found the great write-ups on the oil changes, and even the spark plug removal; but need a detailed explanation or even pictures of how to remove the coil packs to the plugs; I don't want to break anything.

After changing 3coilpacks on my Passat 04 1.8T soo far finally the last one went out. The codes I got are P0301 (which is misfire cylinder1) and the other code is p0420 which I do not know what it is... I think it might do something with cat or something.

I've had my 24V off the road for about a year now working on it. I did some wire tucking and what not, nothing major. Now when I go to start it, it won't start and it will make a popping noise from a coil pack and it starts to smoke.

I have an 02 accent with a 1.5L and it is dropping #2 & #3 cylinders. I changed the coil packs and still had no spark on #2 & #3. I checked the wires going to the coils and had no voltage feeding the coil packs.

Changed the spark plugs on my 2006 Camry today. Everything went smoothly and quickly except for the fact that I broke all the little keeper clips on the connector plugs that connect to the coil packs. I called my Toyota dealers and one said I had to replace the entire wire harness. The other found the connector plugs for around $8 each. Will the broken clips be a problem with the connectors eventually coming off from vibration if I don't replace them? I'm not sure how to replace the connectors if I go that route. How to go about replacing the connector plugs?

I have a 03 250 5.4 with 160k. I just recently replaced #4&3 coil packs. Truck was running great again. Then a few days later the truck was running extremely rough and white smoke from the exhaust. I noticed the pcv valve was not all the way in(pretty much out) put it back in and ran fine for two days now running rough every now and then and the pcv valve is making a vibrating noise but stops if I pinch it slightly. I did replace the plugs a year ago.

Wonder what color wire provides power to turn selector switch on steering column. I checked under dash for fuse 23, and all maxi fuses under hood are good. Also swapped the turn signal relay under dash and no success. I have yet to clean the pins on the firewall harness connection.

B5 Passat, it has the 2.8 and it has been having moments of shuttering so I did a scan and hit 3 engine falts, I did do a clear and rescan so these are new faults.
3 Faults Found:
17801 - Ignition Coil Power Output 1
P1393 - 35-00 - Electrical Malfunction
17802 - Ignition Coil Power Output 2
P1394 - 35-00 - Electrical Malfunction
17803 - Ignition Coil Power Output 3
P1395 - 35-10 - Electrical Malfunction - Intermittent
Right now my guess is the coil pack is going out or loose connection to the coil, this coil is roughly 8 months old so it kinda has me at a loss and hoping its not the coil.

I have a 1998 Passat 1.8 T with 137k miles on it that has been throwing the P0422 code. I've reset it at Schuck's and it has come back. Car is running fine and no rattle in the catalytic converter. Although it could still be the cat, it could just as well be something with the O2 sensors. Don't have a VAG-COM tool to check them directly. Is there some way other way to determine which O2 sensor it might be and/or if it is really the cat?

I have an 2002 GT with a 3.8 in it. Two wires broke on my harness that plugs into the shift solenoid so it will not shift out of park.
I got a new harness and wired it how it was wired before but it is not working when I plug it back in. Is there a way to test the new harness to make sure it works?

I found a decent deal on a 2nd gen prius. But I am going to need to repair the battery. I have already known that I can test and only repair the needed cells (since I looked into the situation when I was buying mine a year ago). Looking at the forums and saw there were a couple of chargers being recommended by the users; such as the supermate DC6 or the Hitec 44151 Quad X4.
I will likely want to charge 8 cells at time at least, as I would ideally like to get the car fixed in a couple of weeks.

I recently failed emission test for my 1999 V6 Passat. I replaced the cats., thermostat, O2 sensors (before cats), and the list goes on. Is there a reflash in the ECM that needs to be reset that only VW can do with their scanner?

Santa Fe 2001 2.4l. How can I check or test a MAF sensor? I replaced the sensor four months ago but now I have the P0102 error code again. I would like to have recommendations before to clean it or replace it again.
