so got a cel coming home from trading my high rise for a low rise. i step on it and hear my exhaust go pop pop pop pop pop pop pop. (i have a catless dp). it usually pops when i redline it but it was doing it a low rpm. so drive home without any noticeable problems and go to autozone and they scan it and say its a 0302 meaning that my 2nd cylinder misfired. gonna take it in to the dealer soon. but any ideas? my car has been running fine.

 

Coil pack more than likely.. Happened to me.. Possibly plug too tho

 

These cars are finicky... The slightest thing could upset them... try swapping back your low rise for the high rise and see if the code goes away.

 

if it does ill LAUGH

 

hahaha thats probably the problem too

 

Hahah .....

The car has alot less drag with the low rise so it's screwing with the Flux capacitor hehe.

 

Try changing yours plugs with colder ones txt me and I'll give you the type and part number. You should be able to get them in Kenner

 

so they had my car for a day and still dont know what the problem is. they said it had nothing to do with spark plugs or fuel injectors so they are digging deepper. they said they are ordering a new spring to see if that will fix the problem. im just glad they are doing all this warranty work because of my mods!

 

What kind of spring? one in the plug boot?

 

i have no idea. so they thought they nothing was wrong and cleared the code and called me. i get it and cel goes off again, bring it back in and was quite irritated. but they did give me a rental car. day 3 in the shop and they have no idea whats wrong.

 

problem found

 

day 4 in the shop. still no idea whats wrong...

 

Have they taken the time to pull the MAP sensor and use a scope to look inside the cylinder head for any sort of obstruction, valve damage, etc?

 

now they think its the fuel injectors. lets hope so
