Drive a EG 6 . believe im running on a b18c5

- Have very bad idle, engine stalls at times when clutch in to shift gears
- Fluctuating idle
- Throttle body air leak (sounds like EEeeeeeeeeeeeee) when depress gas pedal about 40% starting from 10 reading on the vaccum gauge till 0 reading = floor gas pedal
- feel a pulling back when on low throttle about 5 - 10 % , when depress further on it surges forward with a jerk.



Things done -Washing throttle body with petrol (took out whole tb from intake manifold) replaced gasket with paper . (end up the air leak sound got worse BULL SHIT MECH )

- Check on IACV valve (was told by mech its not connected even therefore it couldnt be the problem)

- Mech said the pulling could be the distributors problem . replaced the internals but problem still residing. ( mech drive same car as me also want to bullshit)

- Change Plugs


Solutions?

Would TPS faulty be a cause?
Where can i get a TPS stock (new ) its not easy to find . (any shops to recommend )

Has the TB leak been rectified. As long as leak ARF will be too lean for idling , end up stalling. Poor battery voltage also affects idling. Faulty TPS or accelerator pedal potentiometer could be at fault.
It's good to do a diagnostics to eliminate sensor problems and faulty injectors.

There is one shc driver who diy his ek and post at blogspot. Tb leak is one main cause. Tpscan also be calibrated at certain voltage close throttle and wot. Maf sensor clean also will do the trick coz very sensitive cant touch using bare hands can spoil. Use carb cleaner or electronic cleaner and spray. Get the leak rectified first. I would try get white tape use for tap and wrap it at tb opening connecting to ur air hose/box cheapest way to troubleshoot diy. Muz be snug fit replace the hose clamp if grip not gd.
