ok, 10mpg - driving like a granny!!
runs fine - starts,stops dosnt moan, lowish power below 2k and above 4.5k
just pulled plugs, white ? dosnt add up to me. last i checked no codes but need to check again.....

 

I suggest looking into the egr valve. Doesn't take too much time. lotsa info in
92 3.1 EGR Problems @ 9 mpg Code 32 on my and a few others EGR problems.

At the worst point, I was driving with a feather-light foot and still got a constant 9mpg or worse. It was a line from the egr to the intake.

Its worth a look. Do you have any codes?

 

if the plugs are white that means the car is running dead lean,do u mean the insulator is white,or is the entire end of the plug white?

 

Lets start with the plugs, what brand?

 

right guys thanks for looking, ive fitted new plugs (champion) gapped at .045 - the ones i removed were at .035 (ngk's) the insulator and tips were white though curiously round the outer edge was rather black

ive blocked off the egr

ive played with that bliming charcoal canister

i had a trundle up the road and theres a hell of a lot more power below 2k and higher up now, im guna read codes tmrw, and use it and monitor mpg

i cant smell gas anywheres so im hope-ing theres no leaks

ill update later

 

can u take a picture of the plugs?

 

NGK plugs run really hot, try using AC Delco, they're like $1 a piece and they run perfect for our cars. They'll run half as hot.
