1979-1993 & 94 Conv [Subscribe to Daily Digest] |
Hello Dale,
I'm afraid I won't be much help to you, but I had to reply as I'm in what sounds like the same boat with my '87 900 16v turbo. I'm not entirely sure how close our engine setups are as I've never had the chance to study an '88, particularly in regards to the distributor/fuel injection setup, but sounds pretty near identical to mine.
Mine started out with an uneven idle that would stall out the car if you didn't keep your foot on the accelerator right out of the gate- fixed the rough idle by pulling apart my throttle position sensor and finding the contact points were slightly dirty- a tiny bit of sanding with some 400 grit paper and it was working perfectly again and had my car idling as normal. However, now I've run into the intermittent stalling issue- car starts up perfect when cold, drives great, then out of the blue will stall like someone shut off a fuel line, and won't start again until you've let it cool down. Then, might have some intermittent 'stumbling' while accelerating afterwards. The pure randomness of the stalling has led me to believe its an electrical issue- I've checked the relays at the ECU and they're all functioning properly, (so is my ignition control module and ECU), so I was thinking it was maybe some bad/worn wiring going to the hall effect sensor but I checked for electrical continuity between the plug to the sensor and the ignition control module and I have perfect continuity! My last hope has been that its the sensor itself- Where were you able to find a new hall effect sensor? For the life of me I have searched everywhere online and cannot find one for any classic 900s before 1989. I'm at a loss here, not sure where to go next with this issue. The car was running great a week ago and now I'm stuck!
