Hey guys,
Really appreciate your all's help with this one. I've been working at this thing for the longest time.
Got an issue where the engine will stall at stop lights. Has been gradually getting worse. Car now nearly impossible to drive, stalls at all stoplights/stop signs/stops. Car is difficult to start, usually takes multiple tries to get it started, have to pump pedal. Also have had intermittent issue that causes the car not to be able to rev past 2500 rpm, now consistent as of today.
I suspect that there's been a head gasket leak for a while now but have only recently been able to get that far on my own repair-wise.
Right now engine is running rich in both banks and my O2 sensors show high voltage in bank 1 and low voltage in bank 2. Also showing a P2311 and P2308 for secondary ignition coil circuit in C and D. Gas mileage is in the 6-7 mpg range.
Have checked the fuel injectors and power supply, all with power. Fuel injector resistance is roughly equal for all 6 injectors with no noticeable blockages in injector ports on both ends. Switched out ignition coils in cylinders 3 and 4 with no improvement. Have checked power supply to ignition coils, all with power (but didn't check the ground..)
If there were issues with head gasket / warped heads from previous overheating (with confirmed white smoke, loss of coolant, and misfires most recently treated with Blue Devil...) could this cause fuel to get dumped into cylinders without igniting? The O2 sensor codes and issues with gas mileage are recent, but the car has had issues with performance, starting, idling, etc. for a while. I think most recent issues have put car over the edge performance-wise.
Thanks for your all's help.
Also, my oil light has been on for a couple of weeks, but the dipstick shows it as full. I've had a steady oil leak for a while, although for some reason it's gone now (Blue Devil or thick oil stop leak X 2 applications) I'd say something about it not giving the typical sounds of an engine lacking oil, but the issues with cylinders not firing, inevitable stalling, and irregular engine performance make it difficult to discern if it's not getting oil. It does feel smooth for the most part, but as if there were like... one cylinder keeping it alive at idle sometimes.
