Something wrong with my car, when car is turned on it idles up to 3k rpm then slowly drops down again.

When you try to floor it, the pedal is really stiff.

Ive had the IACV off today cleaned that up but made no difference, it has got to be something wrong with the throttle body.

Can anyone help

Try disconnecting the throttle cable from the TB and starting, then using the lever on the TB to rev the engine, if it works ok, then its a jammed throttle cable...

Do a diagnostics check on the ECU, or just do the paperclip test.

Try a different air mass meter.

WD40 all elecrical connections from the engines sensors - pay most attention to the air mass meter in this case I think.

Thats all I can think of at the moment...

Ah read the first post again...

Definately try operating the TB using the lever on the side of it. It won't just stop working for no reason - most likely to be a stiff cable or jammed cable...

Thats what I thought too - its normally sealed in between some mesh too so you cant touch the internals - it is either a piece of mesh, or wire, that is very fine. There is also a very fine bi-metalic strip in there that breaks easily...

Right with throttle cable take off throttle body it wont idle at all, with it back on it does the revving thing again.
