Engine Problems - 3/29/2008 8:15:30 AM    95mirage   Posts: 4 Joined: 3/29/2008 Status: offline Hey all, I am new here. But not to working on cars. I have a 95 Mirage LS coupe, 1.8l, 5 spd. The car sat for 3yrs before I bought it, I replaced the engine, clutch, Distributer, TPS, timing belt. The car ran fine for about 3 months. Then the mass air went bad. I replaced that, along with the injectors. Then the car would start and run rough. I went out to work on it today, it will start and shut down very quikly. Timing is perfect. I am out of ideas, any help would be very nice. Post #: 1

Have you checked the harness to the MAS? _____________________________ Cheap + Reliable = Not Fast Reliable + Fast = Not Cheap Fast + Cheap = Not Reliable I have found a median.

Have you tried simply resetting the ECU? _____________________________ Cheap + Reliable = Not Fast Reliable + Fast = Not Cheap Fast + Cheap = Not Reliable I have found a median.

Do you know how to check the wiring for the mass air? As far as what voltage I should get, or anything else. (in reply to Sebba) Post #: 5

RE: Engine Problems - 4/2/2008 2:55:02 PM    joy4ron   Posts: 1 Joined: 4/2/2008 Status: offline I am having a similar problem with a 93 Colt (Mitsu engine). I replaced the fuel pump and the main engine relay. I have not changed the MAP sensor.  I did get it to run for a bit by removing the vacuum line from it.  I also noticed that when I start up the engine, that there is an awful lot of water shooting out of the exhaust when I rev it. I can drive it for a bit, and then the engine just shuts down.  Any ideas (in reply to 95mirage) Post #: 9
