I've been seeking help on 'another network' as it were. In that world, it seems to be expected that a man named Steve who lives Virginia will solve any and all 164 problems. I like Steve but he seems to be a busy chap.
So I'll present this issue here to the huge lurker population which was proven last month (or was it in November?). Perhaps someone may have some insights on an odd problem I'm having... [The following is pasted from a post I made to the AlfaBB or somesuch. The "lack-of-codes" issue mentioned in PP1 is exactly that: push the square button in the manner defined by Fred DeMeteo and nothing happens...no slow flash, no codes, nothing. The button switch has been tested OK, the CEL lights up along with the rest of the lights when the "TEST" button is pressed, and the 'service connector' on the passenger side has been tried.] The lack-of-codes issue is tabled in favor of the actual problem where the engine 'surges' -- revs up while idling. (To the extent that you need to be sure that you're applying full brakes if you're in gear.) This is the weird part: if I pull the engine forwards (towards the nose), the idle drops to 'barely running'. If I push the engine rearward, it revs. Sometimes it seems to do the opposite. This is an early '91. No rubber between the plenum and right (rear) valve cover. While the car is 20 years old, it has only 64K miles on it. The problem is most obvious when just started or when cold. I've poked, prodded and disassembled most of the air intake system (to include the oil separator, idle stabilizer and main air intake). It all looks good -- no cracks or sloppy connections. Spark is good too. I've reseated all the plug wires on both ends plus the coil. If this were a 105 car, the geometry between the chassis and the engine with regard to the accelerator pedal or choke might be an issue. But the 164 uses modern cables which aren't affected by the engine position. Has anyone seen anything like this? [End of AlfaBB post.] My experience has been that the Digesti give a bit more thought to things before answering. Please take your time, think about experiences, phone a friend, etc. I would very much appreciate your observations.
