Burning way too much gas...

[AborteK]

I Scanned the car, came back i had a bad TPS (throtle position sensor).

Question i have could this be causing me to run too rich and burn my spark plugs?

Obviously this is the problem im having with idle, 2,000rpm or 850rpm

but could it also cause me to run reeeaaallllyyyyy rich

i have an a/f ratio gauge installed on my 1st O2 sensor on my headder and its reading rich all the time even @ idle, didnt used to be like that.

Any info might help since i have machanical experience but not on Woo's.

well replace that tps and see what happens (or u did it already)

[AborteK]

have not replaced it yet...
will on monday, getting new tps, for $60us

[buddha102]

good write back to us

[AborteK]

well...still bad luck...

Ive Changed

Fuel Filter
TPS(throtle position sensor)
spark plugs
spark plug cables
had a fuel pump change about 5 months back
headwork was done after overheating, machined.
all new gaskets from head-up
did- idle learning procedure

note: i did remove my cat- converter. Dont know if that can cause such a gas usage, never happend on other cars ive had, dont think it to be this!!



car still burning gas, big smoke cloud from exhaust!!!

burns like crazy, a short trip uses up a noticeble amount of gas on my fuel gauge!!!

any any, ideas other than those if done already anything will help a lot!!!!

well after replacing the tps, does the engine light is still on? what about the o2 sensor? check that maybe

[AborteK]

yeah The CEL is still on :@ could be another sensor, but truthfuly its a great amount of gas for an O2 sensor!

[buddha102]

well im not 100% sure if its o2 sensor might be damaged idk, but u better check that CEL on asap see whats up

[AborteK]

must do, see if i can scan it tomorrow again!!!

Hi,

What's the smoke color?

Blue-->oil
Black-->gas
White-->coolant

As buddha102 wrote a defective O² sensor can make a big difference in mileage.
As for air intake temp sensor and coolant temp sensor.

Check all three.

hey guys

I found a Daewoo-GM Authorized Service & Repair shop, they cheked my car, and seems that when my headowrk was done and reinstalled the broke my timing belt tensioner.

This is what was sending my car out of wack.

Once this was replaced, and the timing belt too all was good


I might have to change my wiring but no biggie, a few o2 sensors, spark plugs but it will be fine
