hey guys, got abit of an engine problem here. The car is a 1983 AE71 automatic. New spark plugs, ignition coil, leads, brake master cylinder, front brake pads
When i start the car in the cold, i have to hold the throttle down and keep the revs at around 1200 for around 30 secconds before i let it go, or it will stall..
After that, It will drive perfectly, revs out cleanly. (it idle's at 1100 rpm). It wont want to idle any lower, when i adjust the idle screw, or it will splutter and stall. Standard factory setting is 800 rpm isnt it?
Okay, now under heavy braking the car will stall. If i brake gradually, it is okay, but if i brake hard (like..normal braking), the revs will fall to around 600, and then it will try and catch itself and stall.
I've been told it could be a "brake booster" problem? What could be the fix for these problems? Cheers!
