Installed boost and air/fuel guage... now running really bad

[Dawzey]

hi all.

i have a problem, last night i installed a boost and air fuel, now my car runs really rough and unhealthy... i was thinking that the boost tube may not be air tight but it is. now i tapped into the O2 senser could that be my problem??

last week i got a fuel reg installed and it ran fine but when i drove into my driveway running fine and after installing them i kicked it over and it ran like a bag...

any help guys???

Cheers

if its running rough at idle itd be an air leak more than likely. check the line to the boost gauge, the T piece and the gauge itself.

What did you T peice into?

If you put a T-piece into the fuel regulator hose for the boost guage and it has a leak you will see bad problems, possibly like the ones you experience now.

I see a lot of people plumb their boost guages there and i dont see the logic. 30cm away at the back of the plenum is a hose to the factory boost sensor you can just as easily plumb into.

yes that is what my boost line is into now...

the one at the back of the intake.

it sounds like it is missing... and i have checked all the lines to and from the intake and they are all tight...

help... someone

well gauges shouldnt make a difference theyre just reading things! thats wierd. what does the a/f gauge say?

the car now runs fine, the boost tube was crimped about 10cm away from the guage.

thanks for your help.
