Dude you have a boost leak!!!!!!!! After the turbo before the TB. The maf is telling the ecu that you are moving more air then is really getting in the motor.....That is why you are running so rich........ Your tech need to get on the ball..Or you are not telling the hole story..

 

nah its the tuning man they can straighten it out with software

 

bad107,

First does the car idle high? shut off the A/C when checking. That is the second time for that one.. If not then try this, unplug your maf drive the car see what your afr's are.. dont beat the **** out of it but bring it on boost, low boost setting them compare afr's.

 

there are some more leaks on the car that need to get sorted out.

Intake hose kept coming off the passenger side turbo...not good

I met up with bmoores and we (he)fixed the hose and did some runs but the hose quickly came off again. I got the car to my house, took off the wheel and fixed the hose again. Dropped the car off at the mechanic this morning and having them sort them the leaks etc...

 

Please anwser my questions. So you can get pointed in the right direction, many of us have been down the road you are on. Where are your afr's now? If the leak was per turbo the idle should have been rough as *****, yet I don't remember you mentioning that..

 

I made him do log.. his idle afrs were fine ...

 

The idle was all over the place until we put the hose back on. That sorted the idle out. There is a leak somewhere else for sure apart from the turbo inlet hose. I'm sure the shop will lower the motor and check the rest of the car.

 

I was asking if the idle was high. Not the afr's reads at idle.

 

The shop should have smoke tested the motor on out of the car. Then in the car. My car had some resent afr's/boost issues and it turned out that after smoking the car one of my intercooler welds had a crack about 9'' long. found with smoke the compressed air would not build up enough psi to make noise.

 

sorry the idle was fine on the logs he sent... I think all that happened after that.... but it seems like the problem is between the airbox and the turbos... they put on an intake... did a bunch of odd insertions of aluminum tubes thinking it collapses under boost ... " I was like? " pre turbo ... collapses.. making a woosh sound...( paraphrasing )....

All true...

mechanics pressure tested (the right way - markski way) up to 25 lbs and said it was good.

Problem was the intake...

So my intake pipe is 3 inches...we didn't use the transition hoses from vivid since they wouldn't reach so my mechanic had a piece of exhaust steel made to transition down to the diameter of turbo...then a silicon piece connect the steel piece to the turbo.

The problem was the silicone connection to the turbo. My mechanics think the silicone tube was too thick...its not flexible and needs to be so it keeps sliding off no matter what clamp you use.

They are looking getting a different piece.

 

Makes me feel better. I just thought I needed to hit the weights!

 

smoke tested?

 

Special machine to force smoke into the intake track or wherever..if there are any leaks, you will see smoke coming out somewhere...handy, but can be tricky too. Just because you see smoke doesn't mean you will find the leak right away!!! You still have to hunt, but at least you are hunting in the right neighborhood!!!

 

I saw this guy driving a 78 Caddy that must have had a really bad boost leak inside of his car. Smoke was pouring out of his windows!!!
