Need help with this engine problem...I THINK I FOUND THE PROBLEM!!!
My beater breaks up under load...especially when its hot out.
Just swapped new coils in, engine has 20in of vacuum, tps ramps up voltage just fine and the fuel pump maintains 40psi under all conditions.
No visible wiring harness problems, new plugs and squeaky clean maf.
I even took the egr out of the equation and that didn't help.
Im stumped!
I've had a bad FRPS before but not symptoms like this.
The car idles smooth as glass but sometimes sounds like it has a dead cylinder when cranking.
