Ranger Posted August 13, 2011 Report Share Posted August 13, 2011 Resetting the computer? There's nothing to reset. Just replace the injectors and lite it up. Link to comment Share on other sites More sharing options...
Redrod31Redrod31 Posted August 14, 2011 Author Report Share Posted August 14, 2011 Can't be that easy ...Wow! "how sweet it is" thought I would have at least relearn idle. Any idea on miles per gallon for the Deville after the replacement? Thanks for the info non dealer Caddy repair shops wanted A Grand + to do the job. I figure if I can build my own Street Rods ( old school types, Flatheads and early Chevy small blocks) this should be piece of cake Redrod31 Link to comment Share on other sites More sharing options...
cadillacjeff7777 Posted August 14, 2011 Report Share Posted August 14, 2011 The injectors are probably the bulk of that price. I priced out injectors years ago for my 93 Seville 4.9 and it was around $110 each. 2008 DTS Link to comment Share on other sites More sharing options...

the gold2 Posted September 1, 2011 Report Share Posted September 1, 2011 An outfit on ebay sells re-manufactured injectors only... they do have an 8 set for the 4.9 liter engine. they average about $120 per auction for the set... my 4.9 gets varied MPG 13/15 mostly City 18/20 mostly hi way... probly should do better...
