Car not idling at all with charger on


Recommended Posts

Right i've installed the rotrex as per pictures that ive got of other peoples cars and rotrex's pictures. So may be wrong.

Charger itself is in right place, with 90degree elbow going down towards floor with MAF then air filter.

Pipe from charger to throttle body with by pass valve plugged from pipe to 90degree elbow as per pictures. I have 1 more outlet on elbow but not sure where it goes to, on pics from guy I bought from his is OBD1 and that pipe connects to ISV pipe...but what about OBD2.

Fuel pressure regulator I posted up yesterday has the fuel return pipe plumbed in to it and then from where old pressure regulator was on fuel rail now has a return valve on it that plumbs into fuel pressure reg.

VAC pipe runs from inlet manifold to a t peice that goes to by pass valve and fuel pressure reg.

Does that sound about right as it wont idle at all.

I will be calling Storm tomorrow to pick there brains.

Have ran VAGCOM and no engine faults pop up at all

I havent a clue fom there now...........any help is appreciated

does it smell like flooding????

Also pop the connectors on and off to see if the car works with either the MAF connector and/or the Lambda.. Looking to see if the ECU is getting/not getting flow information from either. Always possible you disturbed or didnt quite make a connector on the new cable sections.

Tried with out MAF and wouldnt start but only bodged connections till I get a new plug from Jim Potter' date=' I disconnected 1 spade connector and it wouldnt start. Not tried lambda sensor as didnt go near it.

have you added bigger injectors as well ?

Standard injectors mate

What exactly is it doing?

Sounds silly but have you double checked all the obvious things' date=' it might not necessarily be charger related

Well its hunting between 1500rpm and 500 rpm give or take. Also when i put my foot on accelerator it does nothing maybe gets rpm to 2500 a most.

have you reset the ECU?

Now ive not tried that.....easy one to do that as it would need reseting

Disconnected battery for about 5 mins and it seems to have made it better......hunts between 600rpm and 1100 rpm and i can rev engine now. Good call Nige, and i'll call Storm in Morning.

Will run VAGCOM again in morning to see whats being said.

Thanks everyone it is very much appreciated

Might be ribbed belt not tight enough as I can see a mark where lad i bought it from had the idler pulley so will pull it off and play with it.

Also ive not cut a bit off the standzard tensioner either.

But surely a slightly loose belt wouldnt cause idling issues
