Okay, I got my car running again, sort of....
But, I have a problem I can not figure out. One cylinder is cold. #2 cylinder is dead. I pulled the plug, and is is wet with gas. I switched the wire. I switched the plug. The plug fires out of the cylinder. The injectors were tested. There is compression. In the same vein, I am not getting good vacuum, so the airflow sensor is not opening enough to keep the car running. Would a nonfiring cylinder cause that? Will I pull more vacuum with them all running? I can not find any more vacuum leaks. I've been through them all a few times. Anybody have any ideas? I'm getting excited again!! Thanks, Jeff |

You say there is compression: how much?
You have a leaking injector What is the fuel pressure? B |

QUOTE(Brad Roberts @ Jul 5 2006, 09:56 AM)  You say there is compression: how much? You have a leaking injector What is the fuel pressure? B Compression is around 100 cold. I can't get the car running long enough to do it hot. #3 and #4 are slightly lower and thay run. This problem started before I had the injectors cleaned and tested. The injector has since been swapped. Fuel pressure is about 30 psi. The problem I fixed was that the fuel pump had been running all the time. The contact in the airflow sensor was shut all the time. It was also cutting out, and I think that was related to the bent pump contact. This was a running engine before I drove it from California to Texas two months ago. Otherwise, the airfllow sensor is unmolested. Jeff |
