Author Message   Gmaan03 Posted on Saturday, September 03, 2011 - 01:41 pm:        My X1 starts fine, runs strong when accelerating. It seems to slightly surge when driving at a steady freeway speed, and acts like it is loading up when just driving around town. When I come to a stop it will back fire through the intake, not always just once in a while. The injectors were cleaned 5k ago, I replaced the engine temp and ATI sensor. I have a force wind intake system. Any suggestions?   Jdodd Posted on Saturday, September 03, 2011 - 01:47 pm:        Checked the intake seals? Exhaust leaks? Air filter clean? How's the fuel filter? Start with the easy to check stuff. Mine was doing similar things, turned out I had a bad intake seal and a bad set of exhaust gaskets. The intakes dry up over the years and will play all hell with your tune.   Gmaan03 Posted on Saturday, September 03, 2011 - 02:36 pm:        Intake seals are new and no exhaust leaks. I'll check the fuel filter.   Psykick_machanik Posted on Saturday, September 03, 2011 - 03:36 pm:        second on the fuel filter. id reset the TPS also.   Gmaan03 Posted on Saturday, September 03, 2011 - 08:02 pm:        SO, I checked the trouble codes VIA a cable link. It flashed 13 Oxy sensor. I looked and found a big crack in my header almost all the way around the oxy sensor! I used some space tape to seal it up and am going to change the oxy sensor and try it out. I will let you know. it is the same as a ford 302 oxy sensor right?   Jramsey Posted on Saturday, September 03, 2011 - 09:17 pm:        Bosch #12014, early '90s Chevy PU. About $20-$25.   Gmaan03 Posted on Saturday, September 03, 2011 - 10:02 pm:        Thanks for the part number it will save me a search!   Gmaan03 Posted on Sunday, September 04, 2011 - 04:22 pm:        I removed the header and muffler, Buell does not have a very good header mounting system? It looks like a failure waiting to happen..... I'll order new exhaust gaskets, weld the crack in the header and replace the oxy sensor.
