Last night I dropped my fuel pressure really low as an experiment...wondering if my FP gauge was bad, cause Ive always had this code 45 issue that comes up after about 500 miles. This is even with a new and functioning O2 sensor. I also moved the connector around that sits behind the ignition module...the one for the ignition module/injectors. I didnt like where it was sitting, and also straightened out some wires going into the connector that looked way too bent right before going into the connector. Anyway, I dropped the FP to 32. I started it back up and started to drive home, and when I gave it half throttle to speed up, the engine coughed and the engine light flashed. I tried again and again and again and the same thing happened. Every time I gave it alot of gas to speed up, it would just cough and die and every time the engine light would flash at the same time. I drove back to work and turned the FP back up to 45. The same thing kept happening, and it would even happen in park, if I hit the throttle to rev it up. WTF? I got no codes and all the numbers looked good. I ended up disconnecting the computer power wire, and went all around and played with all the wires going to every injector, and the wires going to that connector under the ignition module...I moved that connector back to where it was too. The connection there is solid and always was. I bent all those wires around a bit, checked everything else and fired it back up. The problem is gone. What the hell could this be? It was acting like the chip's rev limiter was kicking on, because thats exactly how it works with the extender. The rev limiter will kick in and the check engine light will flash. But this is at like 2000rpm, or really any rpm where I put it under a load. I could rev it up slowly at any rpm, but a quick load would do it. Could the quick jump of the engine be causing some wire somewhere to short? Ive looked everywhere and see nothing wrong.
Any ideas?
