Chevy silverado 1999 1500 4 wheel drive running rough. Check engine light comes on periodically
Find out why the engine light is coming on, it is the info u probably need to fix the running rough problem. Most auto parts stores will read the codes stored in your trucks computer for free, write them down, and ask what they mean and how to correct the problem. If u need more info, return to this site w/ codes for further help.
Is it using more fuel too? if you have DTC's code PO171 & PO174 with the system too lean in (bank1 and bank2) could be the intake gasket leaking? have a smoke test done. Very unlikely to have two oxygen sensors to go out at the same time.
