My sister's 1992 Mitsubishi mighty max started jurking while she was driving the idling would go up in down in park she hasn't had a tune up in almost a year. So I did a tune up on her truck I change the oil & and oil filter, the spark plugs & spark plug wires, the distributor cap & rotar and the air filter. After all this it was still******** and seams to be miss firing. I checked the spark plug gapping it was fine and also the spark plug wire placement it to was ok. I thought I would check the plug compression also I belive the truck is fuel injected but am not sure where they are located. Please help thank you.
