hello, recently bought my camaro and its giving me headache.
i have a 1992 Camaro rs 5.0 manual
it was running fine until one day i went outside to turn it on & it had the hardest time staying on. i looked into it and i replaced a couple sensors, still same problem. i thought i had a vaccum leak so i checked all my hoses and they were all good. i got to my egr valve and it was not sucking air, replaced it & same problem, replaced the egr solenoid, still the same. i have also replaced the fuel filter. one thing i did notice is that once i managed to keep the car on and take it for a drive it bogs down really bad and will not accelerate and sometimes will stall but will start right back up. hopefully someone has some advice

 

What condition are the spark plugs, plug wires, cap, and rotor?

What is the cranking compression for all eight cylinders?

What is your fuel pressure at idle, and at WFO + maximum RPM?

Have you done a cylinder balance test at idle?

What does your scan tool show for coolant temperature, short- and long-term fuel trim, knock sensor activity, O2 cross-counts, etc?
