I have a 87 Saab 900 (8V, 4 dr. 180K mi.) I am having trouble starting it in certain circumstances: - When it is difficult to start it cranks for 4-5 seconds then it catches, idles for 1-2 seconds and dies (the only way to get it going sometimes is to hit the accelerator during it's catch sequence). - Mornings it starts fine having sat overnight for 12 hours. (New England climate) - Once I try to re-start after a stop I have trouble. (The other morning I left my house after the first start went for 5 minutes to the gas station. Shut the car off, filled it up (6-10 mins) and I had trouble starting it). I cleaned the air flow plate and throttle butterfly and adjacent air ways w/Gumot, replaced the air filter. Then I finally installed some tune up components (Dist. cap, rotor, Bosch Plat. plugs). None of these actions improved my original condition of tough starting. However I can add 2 more observations: - It will start immediately after it has been shut off (1-2 min.) - It also seems to start after a minimum rest period of 6 hours. I think it is probably one of the sensors (cold start valve, thermo time switch or maybe warm up regulator). Please let me know if you think of anything, Thanks, Jim
