Hey guys.

I think I have a COP going bad on the truck. It's got a miss accelerating, and the power band just feels kind of chuggy and off. Spark plugs aren't that old, and I've already replaced and cleaned all other things that may affect the trucks performance so I'm leaning towards the COP.

Problem is, there is no check engine light. I would just have it taken up to Autozone or whatever and have them run codes to see which cylinder has the miss. Is there any way to check without spending the $80 at a shop to get a cylinder strength test?

Thanks in advance...

 

If you push it hard , most likley you'll get a blinking light - if you see it blinking at all , you have a code pointing to the cylinder and can get it read.

It's usually a COP or a plug.

Good Luck
