I got a 90 suburban with the tbi 350. it just rolled over 300k on the same motor. i havnt had too much experiance with fuel injection, im more of a carbuerator guy... i know the injectors need to be serviced, any recomendations for cleaning them/replacement injectors??
 
great info and service on tbi stuff here.

he has good links to great places to send for tbi unit mods and injectors.

How do you "know" this?

If their not leaking (dribbling after the engine/pump is off) or have a bad spray pattern (evident with a timing light), don't try to "fix" what isn't broke...

If your having drive-ability issues, diagnose the issue intelligently/correctly before throwing parts (injectors ain't cheap!) at the problem... only to find your WAG was wrong, you're out significant $$, & the problem is still there. :rolleyes:

If your looking to pep it up bit, I've got a Z-Industries performance chip for a TBI 350/700R4 (truck/Sub) combo I'd ship for $25. A bud ran the tune (copied from this chip) in his buggy and said fuel/timing curves were a huge improvement over the stock chip... to the point he stopped tuning.
