I have a 94 Suburban that recently failed smog in California (attached pic of measurements). My check engine light comes in when I'm sitting idling, then goes off when driving, so I pulled code 35. Also, my husband took the pre-heater hose off, cuz truck runs better without, sure had something to do with failing smog (but he did put hose on just while test was performed). I'm not sure where to start with repairs. We don't have a lot of money, but I love my truck, and want it fixed. Any suggestions?

Update...it's been a week since I first posted this message, and NOBODY is willing to reply?? Up until now I've always thought this was a good, helpful forum, but not so sure anymore.
