RUNNING LIKE SHIT!
So i have a 91 NA legacy and the thing doesnt run very well. I pulled the codes and it threw a MAF code as well as a air control valve code, so i replaced both the MAF and air control valve, but the damn thing still runs like shit. When i start it, it starts just fine, but the idle will bounce from 1000 to about 1500 rpms. When the car gets warmed up once i drop below 2500 rpms it vibrates like crazy, and when i stop the rpms drop almost to the point that the car dies.
Any suggestions?

Did u reset the computer after u fixed those. The computer could still be set at the old readings and still runing like crap. Try reseting it if u haven't. Maybe also the coolant temp sensor isnt working like it should.

What kind of plugs and their gaps?
I'd look for a disconnected vaccum line.
Your symptoms sound like my car when I had the brake booster line off.
How does the engine do when you're driving?

I use bosch spark plugs, and i cant remember what i gapped them at. The engine runs fine while driving as long as i keep it above 2500 rpms

Re: RUNNING LIKE SHIT!

Re: RUNNING LIKE SHIT!
I just read your post. Did you CEL not come on? I would feel rather stupid if its just that damn coolant temp sensor
Re: RUNNING LIKE SHIT!
I'm betting vaccum leak, a hose probably came loose somewhere.

Re: RUNNING LIKE SHIT!
Looked for a vacuum leak earlier today and couldn't find squat. Any ideas on ways to look for 'em aside fom visual and listening for air? The "carb cleaner" method?

Re: RUNNING LIKE SHIT!
If you find one let me know I'm pretty sure I've had one for a while but it's small and I can't pinpoint it. If it's what's causing your problem though it would definitely be a disconnected hose somewhere and not a hole.soobrdad02 wrote:Looked for a vacuum leak earlier today and couldn't find squat.

Re: RUNNING LIKE SHIT!
Spent about an hour checking vacuum lines today and didn't find crap. She's still displaying the same symptoms and not showing a CEL. Just to check, I DID replace the CTS with a spare, but to no avail. Ideas anyone?

Re: RUNNING LIKE SHIT!
Have you pulled the codes again after replacing the MAF & IAC valve? If not, pull the codes with the black connectors. Also, I'd suggest doing an active diagnostic with the green connectors to see if anything comes up.

Re: RUNNING LIKE SHIT!
Ive tried clearing my codes, but I keep messing up the process and just get angry. When it gets above 0 degrees here i will give it another try.

You can try just pulling the EGI/TCU fuse, it's fuse 14 in the fuse box near the driver's feet. Leave the fuse out for about an hour.
