I dont know if any of you guys read my other post...heres the link zerothread/293127

But pretty much I forgot to put the spark plug tube seal back in my car after changing out my lifters and oil flooded into my spark plug tubes. I cleaned out the tubes a couple times with paper towels and got most of the oil out and even changed out the wires and the car wont hold idle worth crap and dies out after about 10 seconds if I dont give it gas. Car has CRAZY backpressure also, no clue why hoping you guys could help me out with that? I will take a video tomorrow if you guys think it will help? So pretty much car wont idle and idle is rough as hell, car has crazy back pressure but the car seems to run perfectly fine when I am actually driving it.

So can anyone tell me what they think might be wrong with my car or if maybe I still have oil gettin on the plugs or something which is causing it to still run like crap?

Sorry for such a long post I just need to get the car back up and driving because this is my only car......help me out guys.

Oh yea and I put new ngk bkr5e-11 or something like that in it after I put a new seal in, those plugs wouldnt cause any sort of problem would they?

Actually I bought new ones, ngk bkr5-11 or something like that but I know they are bkr5's. Do you think it is just because there may still be oil in there or could I have messed something else up?

if you have crazy back pressure then you cat is probably clogged up. Pull the cat out and see what it does.

you think I could have gotten some sort of buildup in my cat from the oil in the spark plug tubes and that is why my car wont hold idle?
