hunting idle / poor throttle response

[LVNIT]

I hope your not just using a P28 with the stock rom to run the engine either. Shiit is going to be all over the place

[krasyvy]

well i thought i could use the p28 in place of the p08 but i cant so now i'm after a p08

[krasyvy]

there's a lot more going on in this case than has been explained....

there is?

[bennjamin]

did you plug up/short out the 10+ pin connector on the RHS of the loom ? (3 plugs , one goes to dizzy , other goes to front headlight etc , other is uncconected)

he is,

this is what I was trying to explain

[krasyvy]

yeah I am - I read that the p28 shouldn't cause problems

but I dont really know how good their advice is; wether it's experience or speculation or whatever. And a few of the p28's were chipped so.


Anyways, with regards to the ecu - can i get it repaired or should i just purchase another one?

RHS?

do you mean short out the 10 pin connector on the drivers side of the engine bay?

What does that affect?

And yes, that has been done.

Might call hanny's tomorrow, see what they can do about my dizzy.

OK just to update. After checking the ECU codes...14(IACV) and 8(TDC sensor)

Went down to Hannys to get dizzy checked out.

Robert told me the dizzy looked fine-the bearing inside dizzy would be rooted if the dizzy TDC sensor was to be playing up. But he said I should test my car with another dizzy.

He told me try the FIT and IACV valve and even lent me a IACV valve to try

I cleaned TB put in new IACV and FIT valve and adjusted internal piston in FIt valve (to Hannys advice).

Still the car Idle is jumpy/hunting?!

If its not TPS, IACV, FIT valvle then where to next?

Could teh ECU be giving me the wrong codes cos its P28?

i adjusted the fitv before i gave it too u.

if the ecu is throwing those codes, it means it cant find or has problems with those sensors.. a p28 should run a d15bvtec IMO. u really need a way to measure the mixures and make sure everything is in check - because wrong fuel maps can cause bad idle and everything else.

The FITV knob was screwed all the way in yeah?

[krasyvy]

To clear up Fitv was fine no probs. It is not the prob
adjusted just to be sure as a check

recheck your wiring for the TDC and EACV

if you have TDC problems as mentioned to you before, your car will run like crap. the ROM in you ecu isnt doing you any favours, but you still should be able to rev it so check out your TDC.
