I'm sort of new and have only made a few posts. But I am majorly in need of help!
My truck runs like s*t. I have an 1988 22RE on 35's
This is what happens. The truck initially starts and runs fine. It runs great for a few minutes. Then it seems like it is totally starved for fuel. It hesitates, has no power from start and is basically not driveable. After about 10 minutes or so, it runs fine.
I have done a complete tune-up, the check engine light does not come on, I've tried a different MAF sensor, tps, uplugged sensors to see if any change (no), checked all vaccum lines.
Eventually frustrated I brought it to Canadian Tire (a reasonably decent shop for the USAers). The mechanic fiddled for hours and didn't find anything unusual except for high fuel pressure. I changed the fuel pressure regulator and no change. Very pissed off, I brought it back to the garage and after another 4 hours, he still couldn't figure it out! He muttered something about a TSB for the cold start injector and that the dealer needed to reprogram the PCU. I went to the Toy dealer who said that there are no TSB's like that!
I am so totally frustrated! Please help! Are there any TSBs? Has anybody had a similar problem? Help!
