Strange igition prolem

Hey all; I have recently gotten a very strange ignition problem outof my car. It is a 1988 Camao SC with a 1985 305 TPI from an IROC.

The valve seals are bad, so I installed these little things called "spark plug non foulers" to keep oil from screwing up the plugs until I can do the seals. The non foulers are little screw in adaptors that bring the plug out a little bit from its original position to keep it away from dripping oil from the valve seals. They have a small hole at the end to allow air/fuel mixture to be ignited.

I put in Bosch Super plugs wen I did the spark plug change. The #1 and #2 cylinders dont have these foulers cuz they are OK. All other 6 do.

After I installed the non foulers, by car started to act as if the firing order was screwed up every time I started her, hot or cold. I checked that many times; all OK. The car never did that before the non foulers.

Today, the car started gettng a dead cylinder every time Istarted her, hot or cold. Acts like a plug just aint even working. However, here is the funny part: a minute or so after I start her, thi problem vanishes and she is OK with no problems.

I replaced the MAF and TPS recently, as well as the coil and rotor. Wires are just over 1 year old and the plugs are brand new.

Can anyone help me identify this problem and tell me what I might be able to do to fix it? Thanks in advance!

I don't think you that you can use that many and not expect problems. Were your plugs fouling because of gas or oil? Have you pulled the nonfoulers off to take a look at them?

all 6 cylinders re fouling up on oil. i have to do valve seals. but i just bought some ac delco plugs of a higher heat range, and will install them tomorrow w/o non foulers. see what that does.
