My g/f's 91 NA sometimes dies when driving or when coming to a stop. This only happens when it is pretty cold outside and the engine is not completely warmed up. Once you drive it for a while the problem goes away. I am driving her car now because it scares her. Any help would be great. Kinda broke at the moment so I can't take it to a shop. if it is something i can fix it would be awesome.

Thanks

Does the car have an aftermarket cone-style filter?

At what RPM does it idle?

Does the engine run smoothly otherwise?

 

It idles at a bit over 1000 RPM and no it does not have an aftermarket intake. It runs pretty darn good after it gets going.

 

Clean the MAS and connector, as well as TPS, CAS, and PTU connectors.

And just because it can be a problem without you knowing it, test the resistance across the injector leads - should be 10-14ohms.

 

ok, i will try all that tomorrow when the raining should stop. thanks for the help.

 

I am trying to do the cleaning thing and i assume i have to take the grill off. Is it just the top 2 bolts or are there more. I took out the top 2 and wiggled it but i didn't wanna break anything.

edit: got the grill off. now i can't get the wiring harness off. any help is appreciated.

 

ok, i cleaned the MAS and barely got it back on before the rain. Now the rain won't stop. It seems to have helped a little. I am going to do all the other stuff when the weather cleans up. I found a great reference page though.
