Hi guys what are the signs of a blown engine or a nearly blown engine..... i was told that with compression gone my car wont run but my car seems to run perfectly underboost...the problem is when it is idling the idle is very rough below 1500 so i have to keep it set at 1500 rpms...i do have a power fc installed in my car also so i am controlling the idle from there...the other problem is that my car wont start...it would start only once in 12 hours and during starting it takes a long time to start also....if i shut it down and try to start again it wont start...it would feel as if its about to start and then does down.....i can push the car and start it then it would start.....please guide me guys i am really worried..... https://www.nopistons.com/forums/pub...IR#>/wacko.png

check all you grounds, vacuum lines, spark plugs, wires, and everything else before you start worrying.

Tune up and a compression test

sounds like an ignition problem........ fix it before you really blow your engine up like me



check the wires, plugs, and even the coils.... also check all your ground wires.



did you do anything to your car before this happened? when was the last time you changed your plugs



good luck

Sounds like leaky injectors... you are probably running to rich at idle, hence the shitty idle. Leaky injectors will also flood your engine... pull them out, look for cracks on the pintle caps, and check all o-rings and insulators... and REPLACE THEM before you reinstall.



99% sure thats your problem.

Thanks for your help guys....if my compression was low on 1 of the rotors would the car have trouble startig up.... the other thing is when i floor my car and my boost builds up the car seems to go fine but as soon as i let go of the race the car seems to start missing for a few seconds and then it gets back to the 1500 rpm and is stable there....

Befores doing all this bullshit above do a compression test!!!!!!!!!!!!!!!!!!!!!!!!
