Well here is what happened, i ran out of gas and my check engine light came on and i took it to my local auto shop for an oil change and to install a UDP tha had been layin around for a while. he installed me stuff and reset my ecu and now my car is really jumpy. it feels like i am running out of gas every now and then when i hit the gas and it cause the car to to "buck" or "jolt". What do you think is wrong?

 

is your light still on??? May be a coil pack

 

i reset my cel and nothing has come up,maybe fuel injectors?

 

Bump, I may be having the exact same problem.

 

Could it be the UDP doesnt have the metal contact so the crank sensor cannot detect the position of the crank accurately? Its happened before.

 

Fuel filter/fuel pump clogged from sediment?

 

uhmm...i think i should check my coil pack also.
