So I took my car to brake masters to get my car aligned and I had them put in my exhaust hanger bolts since it was up on the lift and I just had been laggin to put them in, but anyway now whenever the cars cold right when I start it it'll rev up to 2k and then the rpms will drop and it'll die. And if I'm driving and the rpms get below 1k it'll bog down and die! WTF?! Help please!

 

Sounds like you might need to clean your throttle body and clean the IAC as well. Is the car modded/tuned? If so, what mods?

 

I have a tbe w/ cat, cone filter bov and tune. All of a sudden this happened right after I got it back from being aligned. Now the cars impossible to drive. I had to slow down for traffic on the freeway and my car kept dying in the middle of the freeway

 

start simple see if one of the dorks at brake masters loosened up some inter cooler piping id check that first, on a professional note dont take your car to brake masters, i say that because workin in this field weve had a lot of customers come to our shop to fix what the brake masters shop did to there vehicle after they couldnt fix the cars right a second time....good luck

 

Sounds like a nasty vaccum leak. Which BOV are you using?

 

Using a hks w/ recirc but that's not the issue I've had it for a long time. I'll check for a vacuume leak today

 

I'd say HKS is your problem, because I had the same problem with that BOV, but as you just said it was find before. So I'm going to say vaccum leak. Do you have a check engine Light?

 

boost leak, iac gone bad...what tests have you done so far?

 

Ok so I figured it out. My air was slowly sliding off until I took off the maf sensor then the filter came right off. Haha I'm dumb thanks though guys

 

nice
