+1 on the items listed above. Did anybody check into the camshaft sensor? This might be the cause of the stalling and rough idle. |  |  | | 05-01-2007, 02:34 AM | #17 | | Senior Member Join Date: Aug 2006 Location: Central NJ Posts: 2,440 |
I get ~30 city this season and ~35-36 highway. Last summer I got ~45 highway, no city driving. I just had my cat replaced under warranty and am getting +2 mpg. | | | | | 05-01-2007, 03:22 AM | #18 | | Senior Member Join Date: Mar 2006 Location: Golden, CO Posts: 283 |

My 98 ti passed smogged, but my tech said that the cat wasn't running at its optimal. I wouldn't mind getting my cat replaced and get a couple extra mpg. EDIT: nevermind. found it. __________________

If they're the original parts, they're 12ish years old. They may still be working, but not as well as they should be. My understanding for testing these is that you have to take them off the car and hook them up to an oscilloscope. The M42 only has one sensor, right? It might be worth it to replace it anyway. | | | | | |
