heres the situation, my car failed aircare missereably so i left it with my mech for a couple days. 1st thing he tells me is my cars a rebuild, and 2dn thing he says is that somehow my car is burnign too much fuel. my stock cat was clogged , but he changed that and the o2 and it didnt help. and he just put my old cat and o2 back in because he said its burning so much that theyd need to be changed again by next year.

anyway, if you guys could give me some ideas or some things to check that would be cool cuz he said it would take him like a good 10-15hours to go through everything and find the problem.

no internal mods, just prospeed header, bigger piping and intake.

 

 

H22s are more fuel efficient if you turn the motor off while coasting. I found I get great fuel economy when the car is parked and I walk instead.

 

What ecu are you using? Stock injectors/fuel pump? FPR?
