OK, I changed/adjusted the TPS on my 86 Cadillac. The car will start and run for about 20sec then shut off. Im getting error codes E22, E26, E52 and F32. Does anyone know what is wrong now?


Very likely it could be a crankshaft position sensor if you can fire it up and runs for 20 seconds and shuts down it could be your problem which if that is one of the error codes after a scan it can trigger other codes with that one faulty sensor

My 2003 Cadillac DeVille it will crank but wont stay running what could be the problem and it shakes a little bit


It may be the throttle position sensor (TPS). It is located where the intake air (from air filter) attaches to the intake manifold. The TPS connector should have 3 wires. The TPS controls the air/fuel mixture.

I have a 95 Cadilliac DeVille 4.9 high idle , I have changed the ISC and new plugs, wires. Also have cleanded the carburator, what would cause this?


The tps and isc motor have to be set a certain way to work like they are supposed to. The voltage output of the tps must be set with the ics motor not contacting the throttle lever. Then the ics motor plunger must be at its highest setting and adjusted to the correct tps setting of that point. You will need to read a service manual to perform this operation and get the correct settings.
