Hey guys I need some help. I have a 2001 Oldsmobile Alero 2.4. I had a mechanic change out the water pump on it. needless to say i had to purchase a new engine because he timed it wrong when connecting the timing chain back on. I purchased a new engine and had another mechanic install and connect everything. I started for the first time on Friday and I smell a lot of gas. Now I am also concern with when i am driving the car runs fine but when I go to press on the brakes and come to a complete stop the car acts like it wants to kill. I have had all coils replaced, the housing unit, spark plugs and also wiring on the car replaced. the only thing i did not replace was the ignition control module. I need some help as to what could be going on. its a good car and I am about ready to give up. Please help. Thank you in advance.
