Hello all, I am new to the forum and have joined to hopefully resolve some issues with my newly purchased 98 mustang gt. I'm inclined enough to work on it but not enough to pinpoint the issue LOL. I drove the car an hour home upon purchase and during the drive I found a few problems. The sore thumb though is how weak the car is running and that it was stalling when I came to a stop. When I give it gas it it's like the car is running on 20% power throughout all rpms. It spits and sputters as the rpms rise. I changed the plugs today and cleaned the Maf, fuel rails, and throttle body with absolutely no change. I did notice that after resetting the idle the car stopped stalling as bad. Oil was found in a few of the spark plug holes. Any help would be appreciated for I'm on the fence LOL. Thanks in advance!
