I’m having a problem with my van. When I first bought the van it ran but the tranny had 6 things wrong with it and wouldn’t go above 35. It was in limp mode. Then I bought a 99 transmission because someone told me it should work. Well I got it in and now the van will start but wont stay running. The cooling fan comes on but then won’t idle. Codes for the map sensor and cooling switch come up. I’m lost now. I have no clue what to do next.  Any help would be appreciated.

I’m going to have my 2005 Jeep Wrangler’s software updated, will this help or hurt?

Had a 92 ford mustang 2.3L changed engine to the 5.0. After the engine change I noticed that the check engine and air bag light is flashing. Has anyone had this problem, what may be the cause? I read somewhere that it could be a module. What could it be, looking for specifics without having to take my engine apart again. Thank You.

my 95 intrepid is in limp mode. I have checked a few things and found there is no power coming off a light green wire at the trans controle module. That is the 12volt supply wire i checked this on a wiring diagram. Could this be a computer problem. I am able to apply voltage to this wire using a jumper from the battery and i can here the relay clicking on but still no shifting.
