Idle/rev help Stock LQ4
L92 Intake with Holley 90mm TB
Computer is setup for a 02 LQ4 stock tune with EGR, Rear O2's deleted, Vats Deleted.
#1, and 8 Will not fire.
Engine will not rev past 1300ish RPM's
Engine is supost to have 200 miles on it and has been sitting for 2 years. I don't know what more info you will need...
Anybody have any ideas on why I can't rev up. I know there isn't any cuts or nicks in the harness. Unless I have a bad cam or crank sensor, I don't know where to start to look. Motor is to new to need one of those but I can see for sitting for 2 years that it may, I guess.
As far as not firing on 1 and 8. I have swapped coils, I have swapped injectors, I have tested for spark and make sure I am getting a pulse for the injectors all is good. I have compression tested it. my next step is to pull the valve covers and check for valve movement.
I know its long but any help would be greatly appreciated.
