I have had some problems with my truck for a while and I do not know what is wrong with it. The truck sometimes seems to vibrate mostly when I am just parked idling. It use to do it really bad but I got a tune up and changed Ill my plugs and wires and yes they are the right plugs I made sure what else can it be please help!

 

is it misfiring?

 

Well when I hooked the truck up to a scanner it said I had a cylinder 2 misfire but that why I got the tune up

 

and is it still running the same? check the distributor. that can cause a misfire if its not shooting out spark like its supposed to...

a more engine knowledgeable person will chime in here pretty soon. thats about all i got

 

Thanks dude

 

Is it only at idle. Might be your coil pack. Any codes since the tune up. Also the spark plug gap could be wrong.

 

Im not getting any codes and I made sure the gap was right because at first we got the wrong spark plugs so we made sure everythig was right
