I have a problem that kinda corrected it's selp; The motor would surge after it warmed up . You can see th whole motor going up and down under the hood. I took it to auto zone and they said I had a vacuam problem. I took the two screws off the purge valve and it stopped surrging. I then put part back on but did not tighten screws down, aka, a little loose. Can I drive this car untill I get it fixed. Engine light stays on so this is only thing worring me, as I don't want to mess up this motor. Love the car!
