i think the thing we should be concerning ourselves is the fact the issue dissappeared when i sprayed carby cleaner down the throttle the issue went away! its soooo weird!!

Lol I sprayed the carby cleaner down my throttle body and it nearly stalled also but the problem was always there I changed my idle motor last night and still the issue is arising, My mechanic switched over a few plugs (electrical system) and the idle issue went away which was weird he seems to think my issue is caused by faulty wiring harness or incorrect locations

Am Not sure what he switched over but when he switch the plugs to car idle at 900 rpms and never lagged when coming off the pedal and went straight down to 900! Drove well but when i started it about 20 mins later when the car was colder the idle was at a shaken 600 rpms even after revving it. This issue is giving me the shits I wish it never occurred ./

:(hmmm grr this is annoying..

try and find out what plugs he changed.

ALSO, does anyone know how to set the air/idle screw back to standard. i may have adjusted it thinking it could be the source of my problems?

What engine do you have? ill check my manuals and see if ive got one on your engine but if your not very mechanicly inclined you should take it to a mechanic to have it set properly.

Also i noticed on the first page you said you have a CEL reporting a faulty TPS, then when you tested it, it reported no voltage. Did you check the plug/connector for the TPS was getting the correct voltage? if it is then you need to replace your TPS as that has potential to cause your car to rev hunt while accelerating as your ecu is not getting the correct throttle position signal.

Its when the engine wont hold a consistant RPM, instead of sitting at say 750 RPM the engine RPM will surge up and down. search Youtube for "idle hunting honda" and you should get an idea of what its like.
