I need help with a 91 Eagle Talon 2.0 Tubo engine.?

Question

My husband bought this car and the turbo wont spool and the car wont idle right. We had the turbo looked at its perfectly fine. When we start the car the turbo gauge pulls down into vacuum instead of spooling up. Any suggestions or fixes would be great. Could it possible be a vacuum leak? You should also know this engine came from an automatic car and was put into a manual. I dont know if that could be anything; just want to make sure you have all the info. Also the car has no egr valve is that necessary. My husband took the egr valve off his 91 eclipse and it runs the same so we didnt think that was the problem.

Also, we have replaced the mass air flow sensor. Some people have said it may be out of time. Would that cause the turbo not to spool?

I have had the turbo checked out

Answer 1

It sounds to me like the air going into the turbo is not mixing with the exahust air wich is only pulling on one side. The car idle has nothing to do with the turbo, in that case you need to get the car to idle propperlly in order to fix the other problem, in some cases the egr will cause iddle problems I would recomend to have the egr put back on. Once the engine is propperly iddleling you are more likelly regain turbo boost. I've replace many engines and never had a problem when putting one out of an automatic car in to a stick Hope this helps. Good Luck!

Answer 2

The emissions controls for the manual and automatic are different. So is the engine control computer. You are creating a hybrid between the two systems and the engine control computer does not know how to deal with the readings from the different sensors. It could be anything from a simple wiring problem to a problem with the computer.

get your turbo check out.
