Ok,

So i spent a few hours on here using the help and the FAQ and going through all the information on this site to try and diagnose but i've reached an impasse.


Car is throwing code 0607 which is cylinder #2 misfire.

I have a multimeter and i tested all of my coil packs. They're all registering low. I'm getting between 1.12 and 1.24 on all of them. I guess new it's between 1.3 and 1.7

I checked the injectors which are registering 13 which i guess is normal for them.

i replaced the sparkplug in cylinder #2 just because...


The car is shuddering and is misfiring. There is whitish gasoline heavy smoke coming out of the back of the car in pulses at idle.

there is a distinct lack of power but it does smooth out at higher rpm's which i would expect.


I'm kindof out of ideas at this point. Do you guys have any suggestions? I'm considering buying a new injector for cylinder two to see if that solves it beause i know that the multimeter only covers coil issues. Although it seems like it's an ignition issue. The gas is coming out the back but it's not being ignited...

any ideas?

 

Have you tried moving that coil to another cylinder to see if the misifre moves with it? A bad coil can still be within the normal resistance when tested with a multimeter.

 

I actually bought a new coil pack to test it out to see if it was the coil... I've had a coil pack blow before and it seemed like the exact same symptoms so i went out and bought one and plugged it in. No change in the car. I probably should have pulled the code again but it didn't really drive it around enough so that it would register again.

I also moved the new coil to the other front cylinders with the same result.

 

Check the ignition circuit for that coil. Make sure you're getting proper voltage when backprobed and verify that you have good ground. When you're doing these tests, wiggle the wires around and see if any of the values change.

Listen to the injector with a screwdriver or a mechanic's stethescope to see if it's clicking.

If all those check out alright maybe you can do a compression test on cylinder 2.

 

I'm kindof out of my element when it gets this advanced.

Could you explain a little how to check the ignition circuit? I can do some of the more simple procedures but when it comes to the more advanced stuff i need a bit more hand holding

I'll go check the injector now. I put the screwdriver on it and listen with my ear right? I'm looking to hear clicking noises correct?

compression test it out of my expertise range. If it goes that far it's heading into the shop.

I appreciate you taking the time to respond to these questions.

 

Follow the link and download the EC section of the FSM and read up on P0300 and how to trouble shoot a misfire. It will also show you how to check the circuit. It's much easier this way rather than have someone try and explain it.

awesome thx.

It's fixed and you'll never believe what happened. I took the new coil pack and put it on cylinder 4 and then 4 on 2... i swear i did this before and it didn't work... now it's working.

Idle is fine and it was blowing white smoke for a while. I pulled out the sparkplug and noticed that there was a bunch of unburned fuel in cylinder 2. So figured it wasn't getting any spark.

So that's it i guess... thanks for your help!
