Can anyone point me in the right direction? Sure the heater fan blower was intermittent. So I replaced the fan blower resistor. But then, last Sunday, it would turn over fine, but would not start. The odometer read "no bus", so it could not connect with the computer. Checked all fuses. Cleaned grounds. Took it into my mechanic frustrated. He had it three days. Said he started pulling out sensors and parts to get it started. Got it going. But now check engine light is on, and my code reader throws six codes. P1491, PO443, PO130, PO136 and PO705. (It shows PO705 twice). I have scoured the internet and forums, all to no avail as of yet.

Your thoughts would be greatly appreciated. I won't let my wife drive it now, and I don't want to leave town, thinking it might leave one of us on the side of the road. Already used AAA once. HELP!!
