post accident query, car not running smooth

[B-lackGSX99]

So, sitting at a red light behind a Nissan Pathfinder. Suddenly, Pathfinder's reverse lights go on...I hesitate, but give him the benefit of the doubt that he's just going to shift back a touch because someone up front must need a lane change or something. After he's reversed back a few feet, I realize this guy isn't going to stop. I look in my rear view, get the clutch in, and bang...i'm being pushed backwards. Basically, structural damage is evident to my bumper (his hitch went right through it), and my hood got bent inwards so that it won't fully close anymore.

The main problem, is it's tough for me to diagnose the mechanical damage. I've noticed a weird intermittent soft squeal...kind of belty. But the worst thing, is that when i'm driving and maintaining a constant speed, the car will go from stoich to mega lean (to the point where I don't think it's getting fuel) at regular 3 second intervals just for a split second. So the car basically gently lunges at these intervals of fuel, no fuel...it runs perfect though while i'm acceleration or deccelerating. Does anyone have any idea what the problem might be? I'm going through insurance, so it will be taken into a shop, but I doubt these shops will be able to properly diagnose the issue without a little bit of help, especially with the amount of aftermarket stuff I have under the hood.

Also, "I just didn't see you behind me!" is a crap excuse when you're in an SUV with a limo tinted rear window...you did this to yourself, and now it's affected a random individual who fears his car will not be the same again. I'm pretty angry right now. Thank you for any help guys!

Just wanted to say that sucks. But because your car was damaged by this idiot their insurance will have should have to pay for repairs even if you have to take it to a dsm specialty shop. Just dont sign off on anything until the car is completely fixed to your satisfaction. If you do they will have you by the balls and wont do anymore for you. Travis

Hey just read your profile. Did it damage your fmic. Maybe this is causing a problem? Travis

Boost leak test.

thanks guys, and yes, his insurance will have to cover everything. if it had happened in a parking lot, there would be the whole 50:50 fault thing, but this was a clear case of idiocy at an intersection. i am really afraid that they're going to try to screw me, or attempt to pin new mechanical problems on that it's a modded car, or that they were there previously. i'm being honest about this situation, so i am very confident that all of these problems will be easily linked to a result of the impact. I did try to feel around the FMIC, it doesn't seem to have shifted at all, but the piping could easily be leaking a little bit now. a boost leak test will definitely be in store...i wonder if his insurance company will cover things like this, or the fact that it's going to have to be re-dyno'd... i'm taking it in for an estimate later this afternoon, will update then.

Take it to a DSM specialty shop .

I'll give it a shot. There's a shop in town called Apex Modified that does awesome work. One of the guys that runs it has a same gen eagle talon that does a 10.30 quarter mile, supposedly the fastest import (can you call a talon an "import"?) in the province of alberta. Anyways, I hope the insurance company understands me when I say I just want the car to assuredly run as well as it did prior to the accident and that one means of doing so would be to take it to this shop. I've heard in the past that they can be real buggers about that kind of stuff. Also, i'm thinking I might as well do my carbon fiber hood replacement now...i'm sure it'll price out at around the same (if not less?) than the price of a brand new, painted, primed OEM hood. Any suggestions as far as a good place to buy one of those??

Oh, i meant to mention too...when the guy smoked my car, my lower IC pipe got opened up (one of the hose clamps totally slipped off of one of the silicone sleeves)...my AC fan is now melted pretty bad. Would these have been related?? I'm going to check to see if any of my heat shields had been removed by the previous owner (what do these heat shields look like, should I just look for anything between my turbo, exhaust manifold and the AC fan?)...i'm assuming they might have been because the car has 3 inch piping from the intake to the exhaust, and I don't remember having seen any shielding in the past.
