Running rough even with new motor mount


Recommended Posts

My motor mount was completely cracked and shot. So I replaced it with a WEVO SS Motor mount, which for the most part is a racing motor mount. While we were under the car (it was up on a friends lift) we took the opportunity to really clean the wheel wells and sides of the engine. When we got the car back down and I started it, it runs very rough. Not at idle mind you, but runs rough across the rev range. So I am wondering if this is what I get for putting in a racing mount or did I maybe fry or short out a coil pack (with all that water). And if I did, wouldn't I get a CEL light?

Those motor mounts are stiff and will roughen things up. Wvicary is right,a misfire should give a CEL, but if cleaning the side of the engine include the heads and around the coil packs, you could have pushed a week one to far.

If have a soft touch , you can put your fingers behind the tail pipe and see if you feel an even putter, if so, it's your new mount. If you have an even miss you'll feel it and it & it's probably 1 cylinder that's not all connected (coil?), an irregular miss is a different problem. But ,again wvicary is right , ya ought to have CEL for the last 2 problems.

Regards, pk
