When you removed intake manifold to service the PCV system...you needed to disconnect TPS(Throttle Position Sensor) connector to be able to remove the manifold. Did you re-connect it after putting the manifold back? Maf sensor connector almost always make problems at this age. Plug it in and out a f...

Some codes needs time to be set...the others are instant....depends of which dtc is stored and which sensor is at fault.

To cut this agony...read the codes and we will see what is going on.

Read the codes from both...Engine ecu(A2) and ignition ecu(A6)...since your car have them separately.

No we don't get Scandix boxes as we have a Manovlov who has been very kind and helping us this side of the Atlantic with the shipping. Big thanks to him again!

I can't recall if the sensors are the ones that have the wire clipped to them on a connector or are solid wires. If they are the solid wires, then they can break internally. If it is the ones with the clips, again make sure they are clean at the contacts and pushed fully home. Also check the cog whe...

Unplugging IAC valve should kill the engine instantly...unless throttle cable is binding and keeps the throttle opened.

If both mentioned are ok ...then you have a large vacuum leak somewhere in the intake.

U.S market import.
Fuel gauge in gallons,speedometer in miles,different style steering wheel and airbag,ecc in F,passenger side airbag in '95 (E.U market cars didn't had them untill '96)and no side blinkers on the fenders.

... But, after have waited 15 mn idling, the coolant gauge, to the top, came to the bottom and get again to the top. Ect or it's wiring are bad. Ect being bad...the engine ecu doesn't know what is the engine temperature and don't know how much fuel to inject and engine can stall,cut out or will not...
