QuestionQUESTION: I have a 1994 Eldorado, V8 Norhtstar engine. My "Service Engine Soon' light is
comes on and while the car is in park, the engine keeps revving on its own and
then stops, it keeps going as if it's breathing. What does this mean?
ANSWER: Retrieve the CODES from the computer via these directions:
1. Ignition switch ON. Engine OFF.
2. Simultaneously push and hold the OFF and WARMER buttons on the climate control panel for 3 seconds and then release the 2 buttons.
3. CODES will appear in the form of LETTERS & NUMBERS and the display will stop at .7.0.
4. Tell me EXACTLY what displays in the EXACT order in which it displays as if you were video taping it.
5. turn ignition OFF.

QUESTION: The codes went as followed - P019, P023, P053, P071, P083, P095, P132, P137,
(They all had "HISTORY" on the same line as them). NO IPC, NO ACP, NO SIR, NO
TCS, S044, S061 (Again, "HISTORY" was on the same line) then it ended PCM?
I also ran fuel cleaner, and cleaned both sides of the throttle, and it's still doing
the same thing.
AnswerClear ALL the codes from the computer via the climate control panel and check the throttle body and throttle plate for any blackish residue and remove it with an aerosol cleaner. If the problem still exists you will need other directives and pictures to re-learn the computer. Since pictures are NOT allowed on this ALL-EXPERTS website, E-mail: onlineautohelp@msn.com
