heavy on fuel ????

[lightning94]

I cant figure out why my vr is using a weeks worth of petrol in two days, i have tried everything. I have had the scanner on it 5 times and replaced the coolant temp. sender and o2 sensor and changed throttle body and coil pack. I have also checked evry other plug connection and part i can think of including fuel tank and lines. ???

Even air filter and fuel filter?
Have you cleaned out the throttle body?
Not much stuff in the car weighing it down?
Correct tire pressure?
New leads and spark plugs?
Heavy acceloration?

[lightning94]

yes clean and different throttlebody. correct tire pressure. no extra wieght. no heavy acceleration. air and fuel filter are clean. and plugs and leads are ok. i have even taken it to a mechanic for a comp. scan and they cant find anything either...

[delcowizzid]

maybe thermostat not closing making it heat up slowly if not at all, or blocked cat,too small plug gap, wrong memcal in the ecu,fuel pump fuel filter air filter torque convertor not locking up diff hard to turn wheel alignment could be lots of things

check all vaccum hoses also look at how any vaccum operated controlls are working .my vr would lose up to 150ks per tank and it was always number 1 plug lead

I,ll have a look at the cat its the only thing i havnt checked..

[lightning94]

i checked most of the vacuum hoses except the ones for the air and heater controls i,ll have a look at those aswell. I had to replace all the fuel tank breather lines cos had all rotted away to nothing.. but it made no difference any way..

I'm in a similar boat with the daily. VR V6, new fuel pump, filter, cleaned out-fuel lines, new air filter, reco'd injectors, cleaned throttle body, new iac, new tps, new 02 sensor, MSD replacement coils, new map sensor, cai with airbox. New tyres/correct pressure/correct wheel balance, wheel alignment, new diff oil, trans freshly serviced, and all vacuum hoses are new/or checked for damage/wear

All that and Im still lucky to get 350k's to a tank (in a wagon).

I've almost given up!

yea its weird the only thing i havnt tried is the crank angle sensor!!!!! thats the main brain for your spark curve pattern and injecter pattern and shit thats the one im changing this week its basically all i got left to try maybe you should try that one to especially if you have tried everything else it might just be the icing on the cake give it a go.....
