This is my mom's DD, it is a 1997 4 Door XLT 4x2 auto with the 4.0 SOHC. Day before yesterday it suddenly started running very badly and will not stay running at idle. At 1000rpm or higher, it runs well, but below that it sputters and dies.
Checked DTCs and found a P0153 O2 sensor code, bank 1 sensor 1, replaced sensor with no change. Only other code was I think either P0171 or P0174, not sure which, something about the EGR system. (I wasn't actually there, so not sure) It has had the EGR code since we got it, with the subsequent CEL, but it has not effected it in the year+ that it has been that way.
Tried a throttle position sensor with no change either. Where should I look next? Was thinking mass air cleaning, will do anyway, but does anyone know of any particular issue that would cause the truck to run like this?
Sorry if its something common I didn't find this searching, but I got tired of wading through all the single post user's "my truck won't run" threads that had no information
