Yea, i know what you're saying about not fixing it if its not broken.. It sounds like thats what it is to me. If the sound is non-existant during idle.. but you can hear it when accelerating (tick tick tick), then thats what it is. The easy way to check is to start your car when its completely...

I took them into school for a day... didnt help..:nono: Oh, and thanks Malloy, I'll check Napa out.

So i had a boost leak, so then i fixed it. I took my car out for a run and my car backfired in higher RPM's. I logged it with my laptop and I dont know what the hell my A/f's were doing.. they didnt dip down at all in boost.. i mean LEAN LEAN LEAN (18 at one point). WTF, i had tuned out my A/f's...

EGR Cooler, back of the head. Take over the valve covers, use a 1/4" ratchet wrench and 10mm socket (I grinded it down to make it shorter, MUCH easier). Remove 8 bolts, remove EGR cooler (its a plate thing). Clean the mating surfaces, replace the gasket (I made a block off plate), screw down all...

I think its the EGR cooler

Awesome! I'll have to pick it up.

ehh on mine (i have hardpipes, aftermarket fmic and MAFT in blow through) 12, 2.5", 1, 2.75", and 2, 3".

Not bad prices.. thanks shaeff! I'd still choose locally rather than ordering something.. I'm going on a boostleak-hunting frenzy. I want it to stop now. Btw whats the diameter of the factory hose comming off the snail?

Where can i pick up some T-bolt clamps for cheap? Are there any autoparts stores that carry them, or are they only available online? I'm not looking for any irregular sizes, just a couple 3" and a ton of 2 1/2" clamps. whatcha say?

First of all, be careful with the FCD. Second of all we'll need to know what year your car is to know which ecu wiring diagram we're working with, and we need to know if its a k3 or a standard FCD (look for K3 on the product code on the back).

lol, supra90turbo, i wasnt going to say it.

Thanks guys, that puts my mind at ease.

I'm going on a road trip tomorrow, and I'm just wondering where your stock oil pressure gauge sits at around 3000rpms. Mine sits at 20psi. Is it normal for it to drop just below that mark after about 20 miles of driving with cruise control. Thanks a lot guys, anything that ya'll can tell me will...

I agree, hmm maybe i should measure the voltate going to the ECU to make sure its correct?

Just thought i'd add on a question that i cannot find the answer to.. if i did run methanol injection, would it throw off my AFR, and by how much? would it richen it or lean it?

Thanks for the reply Grim, I was thinking about doing that, I guess it cant hurt to try. Any others have issues with it? Anyone else running a pre-89 on maft?.. feel free to chime in.

I've been looking into alcohol injection and i came across this.. http://www.snowperformance.net/proddetail.asp?prod=auto023 Its an alcohol injection kit for cars running the GM MAF sensors. If i installed this kit pre-MAF-T (the black box which converts GM to KV), then this looks like it would...

I've been running MAFT for a few months now, I really like it but every now and then my car will run funny and studder, throwing the CEL. Clearly I know its my HAC because i get codes 31 and 32 (usually, if not always these codes appear together.) I have the MAFT correctly wired to the HAC...

good choice.. patience.

it has a screen at the bottom, i guess thats what he means by filter.
