would i get a code if my o2's are bad??i mean...im getting poor gas milage, but also i have a slight hesitation

 

If they are bad enough, yes.

Monitoring it with a scan tool should tell you if they are operating ok. Check easy stuff like vacuum lines, intake elbow fit. If plugs and plug wires are old, you might consider doing maintenance on them.

 

yeah plugs,air,fuel,cleaned iac motor, has all been done...i dont have a scan tool...maybe its time to invest but i was just wondering if they could be bad without throwing a code....ive been getting a damn p1441 so i replaced the check valve in the back of the vehicle and the hoses....also...the solonoid at the engine...and those hoses...so im stumped

 

Did you reset your ecm after the sol and and other evap lines? Also what is your vac at idle? Are you still getting that evap code?

 

yeah i unhooked the batt. and had someone clear the code out...i was thinking maybe the switch....i know that when i did replace the check valve and the sol. it did help out a little bit...but i think maybe just a little more power is lacking...so im trying to figure this out...
