jvanen Posted January 21, 2005 Share Posted January 21, 2005 have a turbo motor in my 77. My problem mainly happens when the car is warmed up and that is when I try to boost the car it will go to 0 but not past or if it does it just stumbles. However this is sporadic. This has happened to me when it was cold to... but not near as often. otherwise the car runs great and will boost just fine and pull hard. to me I'm thinking it has to be something electrical Quote Link to comment Share on other sites More sharing options...
Guest Magnum Rockwilder Posted January 21, 2005 Share Posted January 21, 2005 If an engine runs better when warmed up than when cold, it usually means the engine is lean. It could also be from weak spark or incorrect ignition timing. It's usually a good idea to let and engine reach full operating temp before boosting, anyways. That way all the metal has reached full expansion and ring seal is optimum. Quote Link to comment Share on other sites More sharing options...
clint78z Posted January 21, 2005 Share Posted January 21, 2005 I would check the Cylinder Head Temp sensor, and connecotr as well. Clean and Dielectric grease all vital connectors as well injectors, afm, ignition coil. Quote Link to comment Share on other sites More sharing options...

fl327 Posted January 22, 2005 Share Posted January 22, 2005 I just fixed this issue on my car, it was timing in my case. Seems with the msd you can run the car way advanced, had to back it down with stock ignition. Quote Link to comment Share on other sites More sharing options...
jvanen Posted January 27, 2005 Author Share Posted January 27, 2005 Cool enough, I'll jump under the hood this weekend and see if I can chase that gremlin down. I appreciate the input. Quote Link to comment Share on other sites More sharing options...
