My check engine light stays on constantly. The only time it goes out is if the gauges all go to zero. Then, I'm assuming the PCM has gone offline. However, this is not all bad as the van runs much better without the PCM. Why would this be true. It idles better, it will pull hills better, and it never hestiates when this occurs. However, after some period of time the gauges will come back on the van goes back to running rough and not pulling hills. When I have the PCM read it reveals that I have multiple misfiring on cylinders 1, 2, and 5. This has been the case for some time. I have had all the ignition components replaced at least twice and it will run smoother for a while and then it goes back to the way it was. I have had the PCM replaced but that didn't seem to have much of an affect on the performance of the van. Can someone please offer some advice on what the problem might be?
have the same problem?
