My car was driving perfectly; now when warm my vacuum is only 10 and it stumblies very badly up to only 5 lbs boost. Will not idle. Only when warm when cold all is well...20 vacuum and 12 pounds boost. JUst as soon as it warms up then it goes to stumbling mode. I checked with carb cleaner and there appear to be no vacuum leaks. Plug wires are firm in place. Since it starts well I assume it is not the cam sensor.
This just started after I installed a new battery and spun out while accelerating. I'm thinking something jarred lose. What should I check? Perhaps the DIS module or the coil pack or fuel filter? THe MAF?
I bought a code reader can someone tell me where it pugs into the car to get code errors?
Oh year 1991 SC all stock but for KN filter panel.
