HIGH IDLE SPEED PROBLEM NOW.

shes up and running after ECU , column, and coil swap but is idling at 2000rpm?   the engine is a swift 1.6 i swapped out 5 yrs ago,   i cant adjust the throttle cable any as its slack.  any ideas why it is or how i can get idle down?  cheers L

Cheers Lambert,   what vac hose you thinking? , I checked the  PSV on the back left of the rocker cover, and it  seems to be fine (it actuates when i put my finger over when running)   i read here that the AIC valve on the side of the throttle body can be the problem?   ive a much cleaner one on my donor car i could swap.  would that be a next step?   shes in for an MOT today so i,m hoping that wont be rotton beyond test.

Did you try the cross head screw with the lock nut
That's how I sorted my revs when I fitted liana throttle body 

hey Jack, you mean an adjuster jet on the throttle body? ive a picture but dont know how to add here,. i see 4 x 13mm bolts holding the throttle body down, i was going to take those out and swap the lot. wish i could attach picture!
worse prob is failed drastically on rot of cab to chassic. arrgghh , new thread for that! 

This one 
 
It worked for me 

oh ok, yes that makes complete sense! the slack throttle cable made me think
no adjustment, BUT its sitting up next to that screw. off to try!
cheers Jack
