Hi,
Today is not a good day. I lost one part of my blinker somewhere while driving and MIL 43 blinked to me friendly with its orange eye
Symptoms: Engine starts with no problem, it is possible to drive but I didn't try to rev over 4krpms. Every attemption to step off from accelerator pedal makes the revs drop to 0 and the engine switches off.

So far I know it's a "Problem With HO2S Circuit Or Fuel System".
I reset ECU- no change.
The car: Prelude 94 VTEC
New plugs, dist rotor, dist cap, wires, fuel filter, valves aligned and so on.
Any help will be appreciated

probably something to do with idle control valves or sensors. Try there next.

 

Code problem solved- short in a white wire of oxygen sensor. New isolation cured that CEL.
Only dropping revs problem left, but soon will be good.

try tightening the throttle line under the hood... it will keep the idle higher, just a few twists of the screw should be enough... i did this on a coupld of civics and it fixed the problem, try it out...
