Cruise no go and stinks
While sitting in a drive through, my check engine light came on. When I left and got back on the highway, my cruise no longer worked. To top it all off, my car now stinks of rotten eggs. I pulled the codes and got it to clear. I still have no cruise control and that god awlful smell is still there. Its that rotten egg smell like I'm running to rich. I don't remember what the code was, but I thin it was 1-2-1. Like I said, it did clear and has not come back for about a week. Any suggestions? BTW, I only get about 20 MPG or so. Is this normal? Car has approx 152k miles.

We lost the cruise on our car after it was serviced. Check the following: (1) the fuse for the cruise, (2) the fuses for any of the pollution control devices, (3) the vacuum hose from the cruise air pump, and (4) the wiring connector to the cruise pump.
The cruise pump is very easily accessed by removing the battery, then removing one battery cable clamp bolt and two tray retaining bolts. Pull the battery tray out gently and mounted to the underside of the tray is the cruise pump. Check the hoses, wires, connectors and condition of the pump. You could disconnect the pump wires and put some power to it to see if the pump is okay. All-in-all, less than 1/2 hour of work that could save $$$$$.
I had a really bad problem with my mileage recently and found that there was a TINY amount of contamination on the MAF (Mass Air Flow) sensor. When I say TINY, I mean I could barely see it. Even small problems with your MAF sensor will cause performance, fuel trim and mileage problems.
Possible solution procedure:
Go to an electronics store (like Radio shack) and buy a can of electrical contact cleaner WITHOUT LUBRICANT. This stuff is made for cleaning electronics, won't hurt plastics and is completely friendly to your MAF. Disconnect the MAF housing from the air cleaner and the snorkel that connects to the housing. Carefully remove the housing containing the MAF, then generously spray the sensor without touching it. If you touch the sensor itself, it could be a $150 mistake. Try to get the inside of the housing without spreading any gunk to the sensor, and when your done, put in a nice new air filter. My mileage went from 19 MPG to over 25 MPG after the cleaning ... also the bad exhaust smell went away.
The entire cleaning job takes about 1/2 hour.
