I bought a new 98 jimmy last week and it is pulling forward like the engine is trying to give more gas then quits it pulls and quits when I go about 50 mph or higher. Very scared and have two children With me. Please let me know what it could be
first thing you're going to want to check is your transmission fluid level. Make sure it's full to spec and the fluid is red and doesn't smell burnt. Don't over fill the trans. marks on the dipstick are for pints not quarts. If the trans fluid is ok you should have your vehicle scanned and look at the fuel trims and also look at the transmission. You could have a trans problem with the lock up solenoid turning on and off.
