97 Grand Runs like Crap HOLY CRAP
Alright I bought a 97 Grand for my daughter who just had a baby and was allot bigger and better for her. It has the 4.0 and Automatic. I drove it to the hospital with no problems and the next day she said it runs horrible. So i told them to take it to check the codes cause she said the Check engine light was on. So they said....... Throttle position sensor, Crank Shaft Position Sensor, and Coil. So I replaced all of them..... the crank position sensor had a little greasy dirt build up on it......... think I may have a small rear seal leak since there is a drip on the bottom of the bell housing....... none the less..... The check engine light went out, and it ran pretty darn good..... the next day, they called and said it runs like crap, jerks then dies..... then its hard to start. Alrighty..... we cleaned the contacts to the computer with contact cleaner and brushes, then used some contact grease.......Then I zip tied the around the computer and cinched down the connectors..... It seemed to run really good for about 3 weeks then its back to running like Crap again...... no codes though....
So,,, thinking maybe the board has a problem or a bad or weak connection......... or????? anyone else had this issue?
