Hi all!!
I have a very sick 93 RT/10 here in the UK. Its running like a donkey and lacks acceleration and top speed. I just had it o a rolling road today and the BHP is well down (about 200BHP and 3500 rpm). It sounds like its missing some cylinders or just that the timing is out. I did change a coil pack last summer before I put it away for winter (the one that serves 6 pots).
We did a compression test on each of the chambers and they check out ok at about 10:1.
One thing we did find today was that all the sparkplugs were totally dry and the insulator was white (as it is when they come out of the box) - apart from Cylinder No 5. That was black and carbonated.
I have run the ignition on/off sequence to get codes and all I get is 12, 33 and 55. 12 means battery recently disconnected (which is true), 33 and 55 are normal.
I was wondering if anyone knew where (or if) I could get hold of the right cable and software for my year of car to be able to run a diagnostics test from the PCM as I think this may hold the secret. In other words, id rather see what the PCM can tell me before I go spending a fortune on parts that I may not need.
I think likely suspects migt be the MAP sensor or the Throttle Positioning Sensor - or barring that dodgy coil pack again.
Any more ideas are more than welome!! - especially if you know where I can get the software and cable. I assume the PCM would tell me more than the on/off sequence?
Oh to live near a Viper dealer!!!...........
