running probs

[reid]

right ive got by the immobiliser probs etc and the cars running again with the 1.8 ECU.

 

but its now running like a bag of shite.

 

if i press the accelerator its as if its hesitating a second before revving, and wants to choke itself if i try drive.

 

 

one more question, ive went from the 1.6 with the EFI cast to a 1.8 without.. but that leavesthe sensor at the start of that pipe without a plug, what goes onto that?

[Stu]

Air temp sensor?

[reid]

think thats it, the white plug at the top of the pic?

 

 

and any idea what this plug is for? found at back right of the engine bay.

 

 

any ideas on my running probs? im assuming the air temp sensor would cause such probs?

[Stu]

Yes the white sensor is the IAT sensor. It needs to be plugged in and working, just like any other sensor. They're not just there for fun!

i guessed that, but to what should i connect it too?

 

im guessing the 1.6 had an IAT sensor too so is it just a matter of finding/using that plug?

 

could that be where my probs are coming from?

hmm turns out its only running on 3.

 

it was idling fine so i figured it sounding a tad rough was to do with the 4-2-1 i had fitted, but if i unplug one of the injectors it doesnt run any different.

 

how do i go about sorting this? is it just a matter of replacing the injector itself?
