I recently did injectors on my truck within the last 1000 miles. Had driveline work done after that. Went on vacation. So I wasn't driving it got back installed my drive line now my truck is throwing 4 codes

0193
1652
2121
2122

I replaced the throttle position sensor within the last year and like I said did injectors also with filters oil change etc etc. Any ideas?

 

Check all your grounds and Battery condition. Clear the codes and see what comes back. With all the hi and low sensor readings something is not happy!
