ISC?? We don't need no stinkin ISC!

I never saw this thread but I did it to my throttle body as well. Works fine. Not for pansies who can't handle a changing idle depending on engine conditions...

i bought my car w/ the ISC disconnected. now that the weather is getting colder here in colorado its becoming more annoying to have done but its still not a problem if i let the car sit for a few minutes.

does anyone w/ their ISC disconnected experience a loss in RPMs if they rev the car up a tad, like say to 2000rpms, and keep the pedal still? when i do that, and the car is still cold, it will drop from 2000 to like 600 and feel like its about to stall, then pick back up and be fine after that. just wonderin if anyone else noticed it.

 

when my isc blew and ruined my ecu, i made a block off plate. i have recently seen problems with my coolent temp raising and bumping down timing. i don't think it was caused by removal of the fiav and bypassing the lines, but you never know. also, i'm worried that i might have a leak coming from the plate, but thats my error, and won't happen if done correctly. my car stalls sometimes when dropping from higher rpms and when i'm turning [power steering], but i don't know if the stalling problem is from the isc or a bad mas. anyways, its another great way to eliminate wires and sh*t from under the hood...

fabbing a plate is too much work, however, is reversible. Bare tb's are cheap, so I did this to a NT 91-94 tb.







the liquid steel was later smoothed out. New tb seals, idles like a champ.
