Hey guys im really aggravated right now because after i was done changing my intake manifold gasket and spark plugs my car wont run right and i got a coolant leak. Here is the thing, i had coolant on my plugs so it was running like crap, so i decided to replace the gasket and while at it replace all the plugs.

Problems

1. My intake manifold is the new style w/alum crossover and i bought it off ebay new but it hadbuilt in o-ring style gasket on it and now i bought ford gaskets and they didn't quite match up with the built in ones (i wanted to use both) so i just used the ford ones.

2. I was told to gap the plugs at .032 for F/I application but the car just totally idles like crap and then dies. Did i not gap them right?

Anyway i spent quite a few hours messing with this thing and i'm just about ready to give up. Thanks for any help

well the oerson who told me that tuned my car and actually when i pulled the old plugs they were gapped at like 0.031 or so and it ran fine

Actually I tought the same thing at first. NA are 52/54. He has a SC like me, .35 is really suppose to be the gap. Try regapping them to .35. Your intake manifold shouldn't make a difference, it's just the upgrade everyone got in the recall. ANother question is did you go to a colder plug ,I assume you did seeing you have a sc. NGK make a good plug(TR-6).

yeag i thought that 0.035 was the right gap but i guess i wasnt going to argue with the guy at the time, but ill try to regap them to 0.035. As far as the manifold im aware that a lot of people do it but my question was which gasket am i supposed to use if yje one it came with went bad? Looks like the only other way is to just use RTV or buy a new manifold with built in gaskets....

Sounds like you have a vacuum leak to me.

So you used both gaskets?
