2001 Cobra acting up

[01_Svt venom]

My car started to have a problem that i have no clue where to start with it. Driving along normal its fine as long as i maintain a constant speed. As soon as i give it a little gas to pick up speed it stutters. It doesn't always do this just every once in a while. I was thinking maybe my fuel pump is getting weak but when i tested it at the rail it read around 40psi at idle which I don't know if that is right or not. Anyone have any ideas on what my problem could be? Car just has bolt ons and gears nothing major.

Check your spark plugs. My car did something similar so I had it tuned and it quit.

could be a number of things I often clean my MAF sensor when I get a rough idle

Start with the simple stuff. Plugs, fuel filter, and clean the MAF.

Mine did this and turned out to be 02 sensors

Sounds like coil going bad to me.

+2, might be more than one.

yea thats where i figured i would start. not getting a check engine light so is there a way to know which coil it is? Also it started to backfire at idle every once in a while so im not going to drive it until i figure out what the problem is.

You could pull all the coil packs and inspect the boots. One of them might be cracked and shorting to the valve cover.

Buy a tester...Connect one end to the COP and the other end to the plug. Should see a light or current depending on which tester you get.

Inspect your plugs as well
