chaos0wnage Posted March 25, 2011 Report Share Posted March 25, 2011 Hey buddy, I'm running an AE92 myself. If your auto electrician said your car is all good (Professionally converted engine) The problem may just be the TVIS setting. if its from the 1988 Corolla FX-GT (like mine) you can control the idle using the screw to the right hand corner of the TVIS (actually on the TVIS block, a bit above the throttle spring) turning it in deeeper will lower the amount of air going in causing the rpm to come down as well as fuel consumption because the computer uses the afm or map sensor to decide how much air and fuel to mix. If it smokes however... just increase the voltage coming off the coil with an ignition booster, but keep in mind that the 4AGE with its wide valve angles will naturally idle high. You will know when the combustion rate is correct as a small amount of water or very little (unless no) smoke is coming out the exhaust. Mine is currently set to idle 2000RPM cold & it drops to 1100 5 minutes later (neutral) in drive the rpm drops to 900, don't worry unless its giving you too any driving trouble. I found that in older 16V 4AGE (~180-250k non rebuilt)warm idle at about 1300-1500rpm drips water out the exhaust, most of the time anyway; should give you about 10km to the litre at that setting. Lower rpms like mine put out about 12km/L Hope that helps. P.S if you turn the screw too tight your 4A will stall and randomly turn off lol.

Anticeptik Posted March 25, 2011 Author Report Share Posted March 25, 2011 Thanks but i don't have tvis. idle adjustment screw is all the way in. Its sits at a constant 2k regardless of temperature, at a guestimate when there thermo cracks is when the hunt begins. Hmm this ones got me stumped, I'm going to try the carby cleaner again tomorrow Quote Link to comment Share on other sites More sharing options...
Anticeptik Posted March 31, 2011 Author Report Share Posted March 31, 2011 ok for lack of better words its got me f@$ked. Ive looked for leaks countless times now, with no results. I did take off the tb and resilconed it up and it droped the idle to 1200 which i was wrapped about, as soon as i touch the throttle it bounced back up to 2k and same problem with the hunt. any ideas??

LittleRedSpirit Posted March 31, 2011 Report Share Posted March 31, 2011 Is the throttle butterfly wandering a bit? Quote Link to comment Share on other sites More sharing options...
Anticeptik Posted April 3, 2011 Author Report Share Posted April 3, 2011 Ok i unplugged the breather hose from the rocker cover to the plenum, the idle drops to ~900 and what i thought was the clutch bearing squeel stops. little confused now.
