so i installed the new tb and a new tps and my rpm is hanging and it idles rough. its also burning super rich. do i need a tune?

 

Did you install a different maf?

I didn't think trottlebodies required a tune. You didn't forget to plug any sensors in did you?

 

I know throttlebodies dont but I dont know about the sensors. Its possible however I doubt it. Did you clean you MAF and Filter? That could have an effect on the RPMs. The running rich seams a little weird to me though. I feel like the sensor would be what would make it rich so a tune may be needed to fix it, but I didnt think they needed it. Could be something weird with sensor going on.

 

I didn't think I needed a tune either. All my sensors are hooked up. I'm not sure what the heck is going on.

 

Im still running the stock maf. My filter and everything is clean.

 

Check your IAC (idle air control valve).

 

Check everything all looks good. Sounds like a monster and runs like a Kenyan. RPM is still messed up though. It's looks like a tune is needed...

 

No cel?

 

Nope. Only when it stalled. P0316. Miss fire on start (first 1000 revs). Reset it and it never happened again. That was a few days ago. Found a vacuum leak. Resetting it one more time and we shall see what happens.

 

Same crap. Think I'm high on exhaust fumes. Still super rich.

 

Weird... Should set a code for idle not at expected rpm...

 

I gots no clue

 

Video of what it is doing?

 

I feel stupid, missed the evap line. just slid a hose back on. But it woulda been running really lean so i tuned it too. Back to where it's supposed to be!

 

glad you found it

 

Ha thanks
