Engine Performance problem
1997 Saab 9000 4 cyl Front Wheel Drive Manual 130000 miles
Ive got a 98 Saab 9000 aero 5 speed, with 130k on it that will not run. The symptom is that it will start, rpms go to 1000 rpms, then promptly dies. If I pull the MAP sensor plug, the car will idle at 1,000 rpms all day long, but will rev to about 3,000 and then die. I replaced the following:
Di cassette, MAP sensor, plugs, fuel pump, fuel press regulator, ECU, fuel filter, apc was inspected, crank position sensor, tested the wiring from the ecu to the fusebox, to the DI, to the crank pos sensor, apc, and fuel pump, most of the hoses to include those to and from the turbo, both oxygen sensors.
I am showing no fault codes except when I pull the MAP plug. If I pull the MAP plug, start the car, and hook the MAP back up with it running, it will idle fine for about 10 min, then die. I have talked to several “experts", including some that specialize in SAAB’s and they are all perplexed without me brining them the car. The problem is I am 250 miles away from the nearest shop that can work on it. I cant drive it around the block, but it idles just fine with that plug pulled. I am desperate for some advice I am fairly mechanically inclined, but this has me completely lost. Thanks!
have the same problem?
