Contour Enthusiasts Group Archives Forums Modifications Zetec Maintenance the engine is running way to lean

just got a new cold air intake installed last week

(thanks jordan) and the car hasnot tried to reprogram itself its running way to lean any cheap way to fix it till 2 weeks when i have enough to get a new 02 sensor

im thinking that will fix the problem i have one new o2 sensor and one old one im going to replace

but for the most part it is running better a little hotter but thats because its too lean

Also...try cleaning the MAF.

ok will try thanks hector

hector i could kiss you (just kidding)

cleaning out the maf helped alot


thanks man plus i switched to a thicker oil
