ok i thought i blew my **** up but i dont think so now cause its not smoking or burning oil. my back spark plugs are kinda dark so i thought i cracked an apex seal so i did a compression test and it was about 90. so i thought that was ok not good but ok so i thought ignition. front rotors are good both trail and lead but the back rotor lead is weak spark any thoughts and help would be great thanks

 

Do you speak english?? If you want help, write better, and explain the problem in detail.

 

ok my car runs like **** until over 3,000 rpm missing at idle speed until 3k rpm i think its a spark issue

 

Thats better. How old are your spark plug wires? If they have been taken on and off many times, the wiring may have pulled away from the plug connector. If they are old I would replace them.

First, I would go thru everything to make sure nothing is loose. Check wires and hoses.

 

Have you checked the ECU to verify there are no stored ECU codes?

 

sorry guys i need to specify im running pfc and i just replaced wires and plugs thanks oh and knock is below 20

 

Has the pfc been tuned?

 

yes for full turbo back, intakes, stock turbos at 10 psi greddy profec b2 ran good until this i think the car is running of the trailing spark

 

Didn't Autotech just blow your engine? I thought you engine was fairly new to be having 90's...

 

yeah thats me thanks, 100's front 90's back cold comp

 

Not bagging on you man. How does it sound when you start it up?

 

where do you live? maybe you can come check it out... im pretty sure its ignition coils but i could be wrong p.s. i used to be in a misfits cover band

 

I live out towards Ramona. I'm out of town right now, but maybe I could come by. I think my buddy Mike went by to visit your ride.

 

yeah mike came bye and didnt realy know ether it doesnt smoke

 

The PFC has a lot of diagnostic information in it. Have you started checking what the PFC is reading for your components?

 

do you mean the trailing and leading volts?

 

dude i told you from the ******* get go stay the hell away from "Autotech" it's like the saying you can lead a horse to water but you can't make it drink...

 

dude you chimed in after the fact

 

thanks guys i fixed it! bad main coil thanks
