Right now I'm incredibly frustrated with my car. There's an intermittent problem where it runs fine, then it runs incredibly bad.
When it goes bad, it happens suddenly, not gradually. The engine gets extremely rough, misfires galore, and the CEL blinks -- scary stuff!!!
When I had similar problems a year ago, it was a bad injector. But that time it wasn't intermittent -- it was constant.
Now, the car runs fine sometimes, and terrible other times. There's not even any warning that the problem is about to happen. It just happens. Sometimes it goes away just as quickly.
I assumed this was a symptom of my botched coil pack wiring. So, today I very carefully and very methodically re-wired the coil packs. Then I drove 45 minutes without and problems. I was so encouraged that tonight I decided to go datalog .... son of a bitch problem came back!!!!
Here's my datalog. It is quite obvious when/where the problem starts.
What should I do??? I do not have another car to use so I'm really fucked until I can fix this.
BTW, I listened to all four injectors with a long screwdriver, and they sound normal.
