Engine GT40 Tubular Intake Install Problems....

Glad its running better,i have a 89 and a 91 and between both cars i have had just about every intake that has been designed for a 87 to 93 Mustang on both cars, not sure why i just loved changing intakes back in the day,lol, my buddies used to tease me,"what intake you got this week??

I had issues for years with the famous idle thing,and when i say years i mean years,sometimes they ran good , most of the time idle issues ect etc, on my 91, the last intake i put on was the famous tubular,gave me nothing but problems and although i had my heart set on it because (have to admit it) that intake just looks bad ass,i could care how well or not well it flows,lol , it was gonna go on my car one way or another, you know what solved all my problems with both Mustangs and i mean solved them completely? about 20 dollars in hose clamps

What had happened is the original intake came with little clamps all over the place for all the miriad of hoses that go on a intake, well since ive had my cars since i was a young uneducated (trial and error) gear wrencher back in the late 80s early 90s i threw those claps away or they got lost, who needs them? i mean the hoses go in semi tight,that should be good enough,right?? NO.

Buddy after putting hose clamps EVERYWHERE on both my Mustang in every hose i could find both of my cars have been running for the last several years impeccably, idling problem?? have no idea what that is, rock solid needle, believe me, i did the smoke test, i even got me a stethoscope,no vacuum leaks anywhere i could find, oh they are there, you just can see them or hear them,they can be tiny sometimes,anyhow that was my cure, figure i would share it, might not be the solution for everyone but it worked for me.

I leave the egr alone on mine other then plugging the intake ports at the lower or using non egr heads. I.E let the computer do its thing but there is no flow from the valve.... even if there is flow its not going to hurt anything when its working correctly. They code 33 from the running self test when you left the reader plugged in showed the valve wasn't responding so it wasn't getting vaccum correctly, you could fix that a lot cheaper then a chip if you want, there's nothing radical on the car that would need a locked in tune anyway and a chip to just delete that is kind of pointless.

I would toss a vacuum gauge on the car and see what you get and the fact that it ran fine before the intake manifold swap tells me it is most likely a slipped gasket. If the vacuum reading comes back low I would order some more gaskets and pull the upper and lower off and see how bad the intake to head gasket slipped on you during install.

This might help determine the gauge readings

You should've asked for the consensus view on Bama tunes.
