I don't think the EGR tube is anything to worry about. If you connect it back to the manifold and tighten it down you should be able to wiggle it. Mine does that but when you connect it back to the EGR valve it reduces the gap.

Add Sea-foam to your gas. That stuff is amazing.

and i guess i haven't mentioned that the car doesn't put off any of the symptoms i'm used to from a car running rich. there's no smoke coming from the exhaust, the exhaust does not smell heavily of gasoline, the cat. is not running red hot, etc...

after doing some research, it looks like that vacuum reading may point to a timing issue. it seems that high performance engines give off a reading like that because of the valve offset where both valves are open at the same time. since mine's a stock engine with no mods, i wonder if something's not wrong with the ignition system. i know i've had problems with my coils and my ICM before and the ICM is a lifetime warranty at autozone, so i may swap it out to see if that solves the problem. and i know my tach doesn't work, but it didn't even after i replaced the ICM before. when you turn the key on, it jumps to 4k and doesn't move but maybe a tiny little bit when the rpm's get high.

is there a way to bench test the strength of the ignition coils? i know you can pull the spark plugs out and ground them to see if they give a good spark, but that doesn't really test the strength.

To test the strength you'd need alot of expensive equipment.

I say if it's throwing blue spark your fine

so it passed emissions. all of the levels were very low. i guess now that i've got the sticker, i'll throw some seafoam in the gas tank, do a tune up and drive it for awhile and see what it does. other than plugs (wires are less than a year old), a fuel filter, and a pcv valve is there anything else inexpensive you guys would recommend replacing? the air filter is new.

also, how much seafoam should i add to the gas tank? or should i do the whole 1/3 in throttle body, 1/3 in gas tank, and 1/3 in crankcase thing?

if you put it in the crankcase you will have to change your oil in 100miles. Put a 1/3 in the tank, and 1/3 through the vacuum system(brake booster hose is the normal access point).
Install the fuel filter after you have run through the tank with the seafoam. It might clog it and it might not.

Hi,

Testing the coils is easy, you just need an Ohm meter (DMM would be best) and find the specs for the primary and secondry windings and your set.

Autozone does test ICM as well as your Coil Packs.
