One last thing does it only act up when the car is at running temp. The coil can be an issue as well, but I found in my experience that coil only acts up when it becomes heat soaked after the car is at its running temperature. I would place washers between coil and heads to fix and help prevent future issues. Bmxridder reminded me of that on my build and I realized I forgot to do that and made a quick adjustment.

unplugged maf and drove to advance auto parts with same problem no change. got to advance and started getting irritated at prices, then my manager buddy who works there comes outside with me and starts looking around. pulls off passenger side pcv line (the only one i didnt replace because i didnt think of it) and finds this right at throttle body:http://i1184.photobucket.com/albums/...B0A8E-orig.jpg

fixed it with a piece of fuel line that was a nice tight fit and drove around for 30 minutes with no problem...i feel like smacking myself in the face now. :facepalm: im still replacing the fuel filter and i do want to get a spare maf because i dont want this to happen again.

thanks guys. if this evil gremlin comes back even after all of this i will repost

i have read about this and am currently spacing it off the head in like two minutes. the coil will have to wait till payday as will the plugs and wires (ngk tr55 $$$)

bigz28man nice motor btw lol

I'm looking to sell my granitllie maf sensor shot me over a pm if interested.

The motor makes music next Friday, no cats, no mufflers, long tube headers, it should be a loud rock and roll concert. Thanks btw.

vids or can i come watch lol

for the granitelli dont you need a tune?

Its plug and play

still having the problem...im lost now. i replaced EVERY vacuum line there is and it still does it especially worse when the motor is hot. it was running ok on a short drive to a car meet. then on the way home all of a sudden at 50 mph cruising i push down a little bit on the throttle and it comes back. get home let it cool for a little bit restart it and go for another ride and i dont even get a mile from home and its back just like the video. i already unplugged the maf and map based it still did it. im really starting to think ignition problem. the coil/plugs/wires are going to have to wait a few days until i get paid though. this sucks this is my dd

Yeah I would do a total tune up. Plugs, Wires and if your feeling froggy the opti cap

I would try swapping ICM's and see if the problem goes away at hot.

anybody got a spare icm? that things $90 on the cheap..

Yea I got one, er prob two :lol:

but ur by the meadowlands correct?

Noo, I am exit 105 area.

:facepalm:

tuesday morning/afternoon ill be in that area you going to be around? how much you want for one?

im gonna go pick up a coil now mine seems as though it has seen better days...try that next

Mine was doing basically the same exact thing as yours. I threw alot of parts at it. It ended up being that the cat was clogged. I seen yours is high flow but maybe do like I did. Shoot the front side with an IR thermometer and compare it to the back. There shouldnt be much difference in temp. I did mine and it was around 300 degrees difference . I gutted it and mine runs like a charm now for about a month.

the cat is 3 weeks old....in the process of changing the coil i noticed that a rediculous amount of heat is coming off of the icm/coil bracket. i dont think that it helps that the coil has the epoxy all mushy its getting so hot...ill post back in 20 minutes

not the coil...this sucks...must be icm/wires/opti....

There is supposed to be thermal paste on the icm. Just because a part is new, doesn't mean it can't be bad. I would definitely look into the cat temps as said before.

After looking at the video you posted, mine wasnt doing much of that popping noise but was bogging pretty bad...I woulde still check the cat anyway, takes two seconds, dont even have to jack the car up. I dont think that the ICM would cause anything like what your having.

Watched the vid, wow. Either a clogged cat (esp with the burning metal/rotten egg smell), a blown out exhaust gasket, or you're running on like 4 cylinders. I'm banking on cat. Try hitting it with your hand or something and see if you hear the honeycomb rattling.

it only does this once the motor enters closed loop. its especially at low rpms under load (like going up a hill) once it starts doing it though then it goes crazy and you have to keep pumping the gas and all of a sudden it will smooth out. probably doesnt help that the plugs that are in it are all gapped at .063 too.
