Air/fuel and backfire issue after replacing timing belt tensioner

[danielkile]

After replacing my timing belt tensioner my car now backfires like crazy and the air/fuel pegs at 10 under boost car runs great when not in boost and idles fine. It's on a tune it ran fine on before.

Have performed a boost leak test? Is there any wiring you may have taken off that hasn't been plugged in or has a loose connection. Did you remove the timing belt when replacing the tensioner. Did you hold cams in place before removing belt? I would check it hasn't jumped a tooth.

 

[danielkile]

I completely removed the belt and replaced everything and reset my timing :/

Also I didn't do a boost leak test but would that cause me running so rich?

Yes a good size boost leak will definitely cause your car to run very rich.

did the car run like that before you changed the belt? if not i would say your timing isnt right since you just messed with it.

+1 ^

It sounds like you might be off a tooth or two on either of your cams. How did you line up everything? Can you set the engine to TDV by the crank and take a picture of your cams for us?

Check over everything you touched to do timing. Double check timing marks are dead on with cyl 1 at tdc. Also go over any vac lines or couplers that you might have removed or loosened during your work.

Alright I'll check over everything, thanks everyone ill let you know what I find!

it was a leak, but I fixed it and it was running super good then about an hour later I blew my turbo...

And just how did you accomplish that feat?
