Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if you cleared the code after doing the work? If so is the check engine light back on? Is the same code coming up?
Thank you. Does the bucking get better or worse if you try to accelerate harder when it occurs?
Thank you. This sounds more like a power train issue. It may be fuel related such as a failing fuel pump or a clogged fuel filter. If you have a fuel pressure gauge I can tell you how to check it. If not then I would replace the fuel filter if that has not been done recently.
Then it may be the pump itself. I have one last question that may help. When the issue occurs does the engine feel more like it is struggling and losing power or are the rpm's increasing like the transmission is slipping?
Thanks. Does your scan tool read live engine data?
It would help if we could know what the fuel trim readings are if possible. If not then I would start with borrowing a fuel pressure gauge from a parts store to check the pressure. It is possible that you have a valve body issue in the transmission, but I do not think that it is the issue.
Let me know. The only issue that typically comes up with the valve body is sticking solenoids and this can happen from sitting.
Sounds good. Thank you.
It is hard to day exactly as so many of these issues can be intermittent. If it is downshifting too soon then this will happen, but it can also be caused by the load at that speed.
