We have a 2007 Toyota 7FGU25 forklift that is killing us. I will see if I can attach a video. But I can send it to you if you want me to. I just need your email address? But when it first starts up, it will go real high in the RPMs and then it'll come down at some point and sometimes it'll do that two or 34 times but then after a few minutes, it levels out. If you make the tilt go front or back or the side shift, either way, then it will cause the RPMs to go up and even kill the engine. But on the mat up and down Leaver, it's fine. We have checked the wiring as well as the potentiometer on the little board on the side of the forklift. We've also tried a new TPS as well as throttlebody assembly. We've also even replaced the regulator with no effect. We're gonna try to clean the connector on the ECU today and see if that helps. we've never seen this kind of problem. Any help would be much appreciated. Thanks, Daniel. [email address removed]

For inquiring mind. What we found was a refining of 4 different things to alleviate the aforementioned problem in the previous post. We had to adjust the regulator mixture along with the potentiometer on the side of the forklift that is between zero and 5 V and also the Allen screw adjustment on the gas pedal. And finally, the timing. Between the 4 of those we finally got the right combination to Make it run normal. I appreciate the one and only response from the kind hearted technician who recommended checking the wires in the loom. Thank you for that. Daniel.

We will try that later today. Thank you so much. I hope that works. We just got back from servicing to Forklifts and we haven't even had a chance to pull the connector off of the ECU to clean it and check it. Make sure there's no corrosion or bad connections. I'll keep you posted. Thanks again. Daniel.
Look at wire loom that is routed on the engine. Wires break inside this loom.
