Urgent rev hunt issue!

[Alexplicit]

Hi guys, had a photo shoot tonight in dubbo. and i now have issues where if im doing under say (including being stationary, either in or outof gear!) 5-10km/h the car rev hunts from between 1500-2000rpm, while trying to drive the car will jerk back and forward as it bounces between 1500-2000rpm until speed is picked up! i have not changed anything tonight, i did not wash my engine bay, i have not changed anything. i was not thrashing the car, as we were taking photos and the police were present! i checked my tps and speed sensor and all other sensors where plugged in?

what is going on??

[Alexplicit]

also add! no cel light is on, and the car idle's fine, and after jerking goes away also drives fine!

Hehe same issue as mine

(b16a2)

Ive been investigating this issue for a while!

First things first!!

1.check your cooling system (bleed it properly)

2. If your car has an FITV clean that up

3. Tighten the FIV if you have one!! up if you need to check anymore info don't hesitate to click the link!

Do the usual. Clean IACV etc.

ok update, had code 7 tps? thought i might try calibrate it, couldnt get any volts at all, middle pin with positive point of multimeter negetive on negative battery terminal. ignition on, no volts no matter where my tps was? took it off visibly seemed fine, cleaned up with contact cleaner. no change, thought i might clean throttle body with carby clener,

WEIRD PART!!!!!!!! AS I WAS SPRAYING CARBY CLEANER INTO THROTTLE BODY, car would rev freely and quickly as per normal conditions, as soon as i would stop spraying it, would start to rev hunt between 1500-2000rpm?

also played with/cleaned MAP sensor? no change.

car is also now surging while driving normal? i could be sitting on 50, then with no change of foot would just die;adjust foot and would raise back up to 50 ect

Ignition system

which bit?

[Alexplicit]

and y would spraying caby cleaner down the throttle body fix the issue?

[trism]

Sounds like a fuel or igntion issue. Carby cleaner is extremely flammable, so it'd be igniting in the cylinder with nearly compression alone. This would be stabilising the idle.

Check fuel pressure, check plugs, maybe change the dizzy cap and rotor button, the coil, etc etc.

the car idles fine. its when i try to rev it is when the problem starts?

[Alexplicit]

and it stalls if it just spray it down. i have to rev it so it doesnt die. so it cant be that flammable.

2 holes In the throttle body 1 on top 1 on bottom now while the car is running place your finger over the top hole see what happens, than place it over the bottom hole if it stops hunting when finger Is over bottom hole pull the unit that's on the bottom of the throttle body a coolant line runs to it... Take the 2screws of the plate at the end of it.. Theres a thing inside tighten it up.. that fixed my hunting problem on my b16a2
