We have a 1992 Dodge Stealth R/T, with the non-turbocharged 3.0 DOHC V6
What is your question?
Greetings: Our '92 Stealth has the non-turbocharged DOHC V6, and front wheel drive. Presently, the car has an "intermittent" symptom of a miss. The car had some other problems recently, and we have been making progress with the replacement of the following, over thte last month or two: water pump; timing belt and tensioner; spark plugs; ignition wires; coil pack; and all motor mounts(since the old ones were shot). Compression was checked, and was around 195 to 205 on all cylinders. The EGR valve responds to a manually applied vacuum. The fuel injectors were cleaned. The fuel pressure regulator was replaced. The fuel filter has around 36K miles on it. The car still has the steady miss, typically after it warms up a few minutes, and the check engine light comes on. (I don't have a code reader for this early OBD system). The car has around 139K miles on it. Any ideas as to what else might cause an intermittent miss? There is no knocking or clicking when the miss occurs. Thanks in advance...

wrong wrong wrong! this is a VERY common symptom with this car and almost nobody ever finds the problem, as there can be SOOOOOO many causes. the OBD1 will tell you absolutely nothing about this problem. Even the dealership will send it back to you unfixed. Good luck.
Super common symptom of an ecu (computer) going bad. These cars from 91-93 ALL had leaking capacitors on the ecu board that would cause this issue. I would check there first and have it rebuilt by a reputable builder or replaced.
It is also common for many places to incorrectly set timing when doing a timing belt job so I would also have that verified.
