Having problems with your 1988 Oldsmobile Delta 88 ?
Bucking engine 3800 v6 olds delta 88 , engine has voilent bucking after about 20 min or so of driving , not consistant all the time but does it eventually code 42 & 44 come up , replaced cam sensor and ..well nothing . new computer (ecm) and ...well nothing , love the car ...not the problem . OPEN TO IDEAS
Check the fuel pressure,also change the fuel filter.check the crankshaft sensor,or replace.It sounds more like the tps sensor(throttle position sensor).It is mounted in line with the throttle axle,on the throttle horn.Of course .with out being there and checking I am just guessing.But map sensor or mass air flow sensor could also cause this.Have you checked the air filter?This will cause the problem,if it is stopped up restricting air flow to engine and mass air flow.,map sensor,and vacuums needed to run the car.If I can help,let me know.
