Engine Mechanical problem
1997 Chevy Cavalier 4 cyl Front Wheel Drive Automatic 188000 kilometers
OK here goes. About a month ago my car started leaking fuel around injector 1. So I replaced the o rings on all injectors and then it stoped leaking. In the meantime it would occasionally backfire, I assume thats from the leaking injector. Worked for a while, then it started running on 3 cylinders. Thought it was the bad injector again, but I did a compression test and cylinder 3 only had 30 PSI of compression. So I continued to drive it and it was working ok as long as you maintained steady speed. Then when I was driving it out to school, it quit! Dead. I towed it to my school and put it on the hoist. Compression test again and all was good 165 in all 4 cylinders. Tested injector drivers with noid lights and all seem to be working. Checked for cranking vacuum, and got Nothing! Should be 10 inHG min. Hmmm so, car wont start, and I think its because it has no vacuum, but not sure how to check for the location of the vacuum leak. Just a guess but I think that the vacuum leak is in the vicinity of the intake manifold as it was backfiring, into the intake I assume, and blew the gasket. But not Positive. Where else can I check for leak in vacuum. Any help will be greatly appreciated. THanks
have the same problem?
