I went and looked at a 86 900S last night. I should be able to talk the seller way down with the cold start issues it has. Classic, idle for 20 seconds and then just dies. Well that I know how to work on so I wasn't put off at all by it. So after five minutes of fighting she finally warms
up enough and the idle smoothes out. Time for a test drive... opps. What's this? I am pushing down on the accelerator and nothing is happening. Then after about 10 seconds the engine, which is idling just wonderfully, slowly goes from 900RPM up to 3000RPM. From 3000 on it
was very responsive. The thing is I wouldn't describe it as a hesitation. This is all happening without the car even being in gear. I pushed the gas and it didn't bog down or anything. You push the gas and it just keeps on maintaining a perfect 900RPM idle. I'd say the delay was about 7-10 seconds. Each time. Wait and then verroom up to 3k no prob. But if you didn't push the pedal far enough you'd get nothing. If you push the gas down for 3k you have to wait but after a few sec the car will respond with 3k, however if you only give it enough gas for say 2000RPM nothing will happen. It just keeps idling in absolute indifference to your request for
revs. I looked for any vac leaks and everything was fine. Unfortunately I was not able to get it out on the road to see if it would respond better after a little driving due to a massive loss of brake fluid. Anyone have any idea what might cause an acceleration delay like that? Again this was a 86 900S 5 speed w/ 185k.
