When I go to start it inn the morning it kicks and sputters like the timing is off or the fuel mixture is wrong then after a few tries and giving a little gas it will go and rev normally and sometimes works fine all day and sometimes it wont go when you give it gas? the throttle body was removed and cleaned (was dirty) the MAF sensor was also cleaned. The transmission was rebuilt and the problem seemed to start shortly after that. I noticed they added maybe a litre too much fluid. Could that be related?
JA: Does the engine
stall right after starting? And what about hesitation or jerking during acceleration?
Customer: Once it starts its ok and doesnt stall. There is occasional hesitation but it is an intermittent problem. Some days there are no issues once you get it started other days there is but it is now always hard to start
