I cleaned the MAF with MAF cleaner. Then the problem started
Car had been running good on the road; some minor stumbling between 1000-1200 rpm
Problem troubleshooting; What I've tried so far:
No CEL Disconnected MAF; would not run New MAF sensor; reset ECM by disconnecting battery for 30 minutes; no luck Disconnected MAF; would not run Disconnected battery over night; no luck Swapped out fuel pump with known good spare Visually checked for vacuum leaks; not that many hoses No CEL
