Car Trouble

[Nate_R]

I was doin a pull in third onto the freeway and felt a kinda clunk, or stutter. My car started deccelerating and I pulled over to see what was wrong. Popped the hood and couldn't see anything weird and checked all the hoses I could see. It starts up fine but slowly starts getting worse (it starts wavering in rpm's), and won't accelerate past 1.3k rpm's. I thought it was just a vac leak but throw me any ideas you guys might have.

Are you a 2.8 or 1.8t?

[Nate_R]

1.8t, I went the APR route with a gt28rs so it has all those mods. If you need any more info just let me know.

Could be multiple things, simple as a intercooler hose poping off, or a boost or vac leak, or N75 valve. Start with this might help you get home later so you can take it up higher than 1,300 rpms. Pull the MAF plug and the sensor before the throttle body and see if it helps. I had a similar problem happen to me but didn't want to diagnose it on the highway, but with doing that you will be able to stumble it home and check later. Hope that helps

Thanks, I got it towed unfortunately, but I'll check it out soon. I'm really hopin it's just a vac leak cuz I think I had a small one before this happened but we'll see.

possibly could be a coil-pack? If a boost hose came off it usually wont run at all...

Turned out to be the MAF so, not a huge problem thankfully.
