I started having problems with my 91 buick regal. It ran rough, stalled when stopped at lights, idled rough, jerked or sputtered when trying to hold a constant speed while driving, and used a lot of gas. I changed the O2 sensor, it got better but did not fix all symptoms. Bypassed the converter, still having issues with jerking/sputtering while driving and now using way too much fuel. I was told it could be the TPS. Is this correct?
have the same problem?
