Spark Plugs

[phatTSi]

Ok heres the deal, I picked the car up today from the dealership they were putting in a new transfercase. When I picked it up I had to change the plugs cause i had fouled a plug (NGK bpr7es). Anyways I did this and then I started driving it and I hit about 3000 rpm and it started to studder like i was hitting fuel cut but less violent. So I went to the parts store and bought more plugs and changed them and then it was fine and then i was driving and then it did this again. I'm not really sure whats wrong. I believe I keep fouling plugs but I am not positive. I had one of my friends call his brother who has a 608 hp talon, and he told me to just change the plugs out for a couple of days to clean it out. If anybody else has any ideas i'm up for about anything to get it running back up to par. Any help is appreciated thanks.

It depends if they are getting fuel fouled or oil fouled. If they are oil fouled, than you probably have a ring or seal problem. if it smells like gas, you could have a stuck injector. What color is the plug?

They are oil fouled i believe. The head and bottom end were just rebuilt 5000 miles ago. If it is the rings how much would it cost to fix this and could i do it myself?

You need to do a compression test first. And also if you just had everything done by a shop, I would take it back to them and ask them.

I will get my compression test asap and if that comes out to be fine does anyone have any other ideas as to what would be causing this?

Ok my plugs aren't fouling anymore but i'm still having the problem. I was wondering if it could have anything to do with my coil going bad?

DId you find the problem to your car? I'm having the same problem too with #2 cylinder, I don't think it's my plugs - my problem started right after HKS camshaft install. Timing is perfect. Plug wires are new (double-checked with extra set). Compression 145-155-145-145.

bosch +4's sucked in my turbo car. Prolly great for your n/t, but I just put in NGK's and it runs hella better.

the +4 aren't any good because anyone that knows anything about electricity is that electricity always take the shortest path so on the +4 its only using one of the tips.
