Miles - 123,000
No fuel injectors have been serviced
I was not at the shop with my husband, he says they did not chk either fuel trims or O2. Just codes mainly. And cleared them, to recheck them again.
This problem seems to happen all the time, but most noticeable at idle or low speeds. Once in a while will idle better than other times.
As for what has been done to the van so far once it began to run badly
1st we changed plugs and wires and air filter.
After that van still ran roughly but seemed a little better. Code light was still on so we had the codes read.
2nd changed coil, Mass Airflow Sensor, and EGR Pressure sensor. Seemed to run a bit better again, but still has the misfire.
One note: while changing the plugs he accidentally broke one vacuum line that had to do with the air conditioner. It made all the air just come out the defrost. But he also fixed this and the air works fine.
One more thing the Mass Air Flow Sensor or maybe the box will hum or vibrate very loudly once it gets warm or hot. The old one did the same thing. The new one does it as well. What could be causing that?
