1995 Bonneville SSEi
I have a 1995 Bonneville SSEi 3.8sc. One big problem I have is when the outside temperature reaches around 90% or above and after the car is driven for a few minutes it starts to die out and eventually I can barely keep it going. If i step on the gas it will not respond, it will jerk back and forth like I am taping the gas pedal. I have had this problem for 2-years. If I put the car in neutral when i am moving I can rev the engine but it takes a few seconds of pumping the gas before it revs and then it will only go to a certain rpm, i think around 3.5 or so and the break up. I have had fuel pump and filter checked and both are ok.
I have heard possibilities of things like Oxygen sensor, Super Charger, clogged catalytic converter, bad coil.
Any help would be appreciated.
