Replacement manifold on the way, ditto new gaskets just incase

I found the problem that had caused it to get worse - my replacement ICAV has literally fallen apart. Refitted the old one and sent a complaint to the seller and got the most broken english reply asking for photos, which I had already sent

Have you checked your throttle cable to see if it is too loose or tight?

I have cleaned out IAC valve, throttle body, map sensor whack, done plugs, done Valve Clearances, Injector cleaner and fuel system cleaner, checked VAC pipes, checked Throttle position sensors and still no joy. I am now thinking it may need one of these items replacing but cant be bothered throwing more money at it chasing a hunch. These items are either : new IAC valve, new map sensor, 1st Lamda sensor, decat it???
Well finally I have fixed the god dam issue!! Yesterday got round to fitting my Tanabe Medalion Exhaust and Berk High flow cat. Completely transformed the horrible sluggish pick up from low rev, shaky idle, kangarooing and recent stalling when pulling away at low revs. Old exhaust had a couple of holes, was rusted out and catalytic convertor had collapsed and was just full of metal and rust. Car idles fine now, no shaky idle, no kangarooing and much better low revs acceleration and throttle response. Personally I think it was the Cat more than the exhaust.

Glad you sorted your issue rickya, must be night and day now

Mines still going annoyingly, fitted replacement manifold and although exhaust isn't blowing now its still not playing ball.

Hesitation wise it's almost like it has extreme heatsoak if it gets parked up for a moment and when its first turned on it just wants to cut out rather than idle.

Bought a low mileage used throttle body now with TPS so will see if my answer is there, fun fun fun

Are you running the standard original catalytic convertor?
