Problem Actually solved completely running as of today, disregard all other posts
Problem ended up being the fuel injector seals were leaking, due to the aftermarket intake I bought. One of the seal seats was to large and cause a leak only below 1000 rpm, also causes slight misfires at idle and while revving
Problem not solved, I can hear a hissing noise right before the car dies near the intake manifold, I just replaced the injector seals
NOTE: YESTERDAY IT WAS RUNNING AT 14.0 AFR
Well I just got my car started after almost 2 months of tinkering, ended up being the battery was to low and not providing enough current.
BUT NOW! I am running extrememly lean at idle ( i cannot drive the car it is brutal ) 18:1 +
when i first start it up it runs fine sits perfectly between 14.5-15.2 @ around 1500 rpm, after a little bit the rpm comes down and then it runs very very very lean and starts to stall.
Things I have replaced:
Oxygen sensor
Coolant Temp Sensor
Battery
injector cushsions (rubber seals on intake manifold)
Wiring harness ( currently have a brand new wiring specialties one in )
Things I have tested:
-Injectors ( they were recently sent out due to one of them leaking )
-Fuel pressure ( 3 bar ) - wondering if my fuel pressure gauge is wrong…
Things I have checked:
All my clamps, couplers and vacuum lines
Reset Timing the proper way
right now the ECU is showing three codes:
Knock sensor ( code 34 )
Ignition signal ( code 21 )
CAS ( code 11 ) -> just got this one Jan 15th thinking this is the culprit
Any Ideas?
