I have 97 Buick leSabre and it is bucking and skipping mostly going up hill when you ask for power but as I'm driving with the code reader plugged in I don't get any fault indications.
Do you have any suggestions?
Answer Did you just fill up? Sounds like either your fuel pump is going out, which will not set a code. Or an injector or coil. Most of the time coil or injector will set a code. You might have to have it put on a diagnostic machine. Let me know.
