40mph plus I lose speed and need to press gas to regain. Alot of jerking at slower speeds need to know if or what this could be I feel as tho my car suched air down and loss of power or something anything I can answer iv prob done but I need help. Iv tryed timeing the car btw it was off time so I changed the spark plugs from bosh plugs to the ones it was supposed to have in it. Bought this car acting up like this it has only 75k miles on it it had a couple problems I fixed a hot wire that burned out to the break lights and made sure there wasn't anymore messed up. Oil pass valve I fixed as it was shooting oil out all over under neath the car and exhaust

anything would be much appreciated thank you

Is the check engine light on? If so, have you checked to see what codes are stored in the computer? Have you checked fuel pump pressure to see if it is within the manufacturer's specs? Have you checked to see if the catalytic converter is plugging?

It had a 02 sensor code thats about it I reset the code and the car seems to wanna die I took the breaker bar out from behind the battery and disconnected the MAF sensor and drained the car of its energy then but back to gether to try and get it timed again but again the distributor did nothing in changing the performance of how the car was running very odd.
