Default Yes Another Misfire Thread this ones weird.

Hey guys I apologize to do this to you but I'm having some misfire issues. All started about a month ago was at tracking the car. Came around a turn hit the throttle CEL came on car felt like it dropped a cyl. Pull the codes faulted cyl 1 misfire. Swapped the coils with 1 + 2. Drove again same thing happened pulled the codes now fault cyl 4. Hard faulted 4 many times after. Pulled the plug looked really screwed up. So i changed plugs, boots and coils. Problem solved?? Put around 200 miles on it no problems.

Fast forward to track day this weekend. Got about 8 laps gets CEL drops a cyl again. Faults Nbr 4. Spoke to a few people they say dirty fuel injector. Cleaned the injector by applying 12v to injector and back flow all the crap out of it. Cleared codes, go to start car wont run and faults Cyl 5 and sometimes 6.

Started it today very intermittent. I can hear it running good then dropping out on and off as I rev still faulting 5 and 6.

Any ideas?? Maybe O2 sensor? Anything else I can look into?

Check to make sure you have good electrical grounds.

So just an update that may make more sense. Tried to start the car today from cold wont idle without my foot on the gas. Decided to look at my o2 sensor voltages. Cold they both read Bank 1: .920v Bank 2: .960v. Car starts to warm up will now idle on its own. Once it reached operating temp. Bank 1 fluctuating from .1 to .9 Bank 2 sits at .960v. When it stops misfiring which it does here and there they both fluctuate between .1 to .9v respectively. Once i hear it drop out again back to .960 on bank 2.


Thanks in advance.
