Car jerking under load

My 01 grand prix had the MAF go out after finding a buyer for first born child l bought the sensor an replaced it. The code is gone an the light stays off now but when you go up a hill or try to pass the car jerks real bad untill you let off the gas.l'm not getting any codes when l check it.the light is still off.l changed fuel filter an spark plugs an added Heat to gas still have the same problem:banghead:

Disconnect the battery negative cable overnight. Then see what it does the next day.

l was wondering if that would help! l'll try that as soon as we get this Ark project done or it quits the rain. Thanks for the reply The good thing is we saved about $15 on washing the vehicles this week end an got a free bath Always look for the silver linning if you cant find it repaint it!
