twin scroll
I was just wondering if anyone has eliminated thier vaccum lines and kept the twin scroll in. I have an 88 TII and after eliminating the unnessecary lines, the car starts, but idles extremely high. I was just wondering if the twin scroll not being removed, will cause such a problem....Thier is also a bolt missing around the lower intake manifold section, which we think may also be allowing air into and causing a leak.....
any ideas PLEASE????

sorry,
Im not driving the car at all....its been sitting for like 2 months now....
the twin scroll has not been touched yet....
we did the throttle body mod...as explained in some "how to's"....
the o2 sensor was also fucked up
we had to attach a new connector....we then reattached it....
could the o2 sensor have anything to do with this?

Does this car idle high AFTER the engine is fully HOT?
A little more detail on what vacuum lines were removed and what you did at the end points of the vacuum lines. Like did you cap the end points? All the vacuum lines removed?

Throttle body needs to be taken off and the fast idle screw and maybe the throttle stop screws need to be adjusted. Thats if there is indeed slack in the throttle cable verifying that the throttle cable isn't holding the throttle plates open. Well, maybe the throttle body does not need to be removed. You could chunk the intercooler and run some pvc b/t the turbo output to the throttle body intake and then you'd have room to adjust the throttle stop screw, fast idle cam and fast idle screw while the engine is idling..
Might spray starter fluid around the intake manifold prior to the above to confirm no external leaks. I thought the intake manifold was held on with studs and nuts, not bolts. Sounds fishy.
