I'm thinking vacuum leak too, it would cause the idle to be low or stall but wouldn't have much effect at higher rpm. It wouldn't cause a code (immediately anyway, eventually, but not right away).

 

just FYI - in case some one hid one of your tools.....

 

Come on buzz don't scare me like that.

 

Can someone point out where the ground wire is for the engine? Ive heard its the driver side. I can see a little screw above the driver side firewall heat shielding and it looks like something like a ground wire/nut could go there.

 

It is bolted to the drivers side cylinder head on the aft surface which is a flat wire braided looking thing that is attached to the fire wall with a bolt. Did you attach both coil connections?

 

Yes the coils were connected. I know it has the symptoms of a vac leak but I've checked every connection I know. Unless there is a wire back there that is commonly missed. I did disconnect the passenger side spark plugs from the head when i changed the gasket. If spark plugs happened to be switched, would i have these kind of symptoms? Though Im fairly certain I have the wires back correctly. The length of each wire gave it a way but perhaps one just appeared shorter/longer than the other upon reassembly.

 

You can also make a quick ground with a battery jumper cable from negative battery post to good metal on engine. Also time to check all the fuses underhood.

 

Here is the main engine ground
Make sure the iacv connector is connected (its easy to bury it upon reassembly)
Cylinder head ground d/s

 

Ah I think that might be the culprit. I noticed that same nylon wire and it almost cut my hand. I see in the photo that its bolted to that the screw(drivers side) i mentioned. On my truck the two are not connected. Could this be it?

 

Okay, just had my brother over here and he's more inclined with engine sounds than I am and he says it's misfiring. I checked that ground again and it is connected. I'm thinking I missed a connection on the coil pack. I know there are two connections on each side but is there another one? Do the two clips have a tricky way of securing? I thought they were connected correctly...
