txpath4x4 Posted October 17, 2015 Share Posted October 17, 2015 Hey guys I am getting codes 51 and 33. Can they stem from the same problem? Or one cause the problem. Also injector circuit code,Electric connection or possibly plugged? Thanks guys Go figure, try to sell the beast and she wants to start acting a fool Link to comment Share on other sites More sharing options...
RF600 Posted October 18, 2015 Share Posted October 18, 2015 Obviously she likes you and doesn't want to be sold. One or more injectors is out of spec. Mine has the same codes. You can ohm out the all the injectors using the plugs near where the upper radiator hose mounts. Do a search, there are a thread or 2 about which wires to use. 1 Link to comment Share on other sites More sharing options...
txpath4x4 Posted October 18, 2015 Author Share Posted October 18, 2015 just OHM'ed all 6 injectors... 2 of them are at 115 OHM's...i have seen a few people post 20-30 ohms when it bad. i guess the old Girl wants to prove a point. on a side note; anyone ever hear the old saying, " if it starts running better than ever, hold on cause its gonna crater?" yeah that is exactly what happened. has been running like a top, not anymore Link to comment Share on other sites More sharing options...
Precise1 Posted October 18, 2015 Share Posted October 18, 2015 Tell her you won't sell her, and enjoy a great running Pathy again... Yeah, sounds like a couple of injectors died on you, but it is suspect that two did it at once. B Link to comment Share on other sites More sharing options...
txpath4x4 Posted October 19, 2015 Author Share Posted October 19, 2015 suspect how? i ohmed them at the injector itself. thinking i might have a bigger issue coming? Link to comment Share on other sites More sharing options...
adamzan Posted October 19, 2015 Share Posted October 19, 2015 Looks like you need two new injectors. 33 is for the o2 sensor. If you unplug the o2 does it run any better? Link to comment Share on other sites More sharing options...
txpath4x4 Posted October 19, 2015 Author Share Posted October 19, 2015 I wouldn't be able to tell. It's hitting like a jackhammer right now with the bad injections Link to comment Share on other sites More sharing options...
Precise1 Posted October 19, 2015 Share Posted October 19, 2015 suspect how? i ohmed them at the injector itself. thinking i might have a bigger issue coming? No, just odd that 2 went out at the same time... 1/6=16.7% which is normal odds, but 2 at once is 1/6 * 1/6 or 1/36 (2.7%) that they fail at the same time, unless I screwed up my math. If they ohmed out bad, replace them and go from there. Make sure to color match them, the spray pattern and whatnot seems to matter. B 1 Link to comment Share on other sites More sharing options...
txpath4x4 Posted October 19, 2015 Author Share Posted October 19, 2015 Yeah I am gonna get a whole set of refurbished ones off eBay, I don't like my odds of another going out, especially if someone is testing it out Link to comment Share on other sites More sharing options...
Precise1 Posted October 19, 2015 Share Posted October 19, 2015 Not necessarily necessary. I bought an R50 4+ years ago and an injector failed in the first year. I bought a full, used, replacement set from a wrecker (same color code) and only changed the one. Not a problem since, with the replacement or the 5 original. Do what ever makes you comfortable, but my attitude is this: If the injector is on the driver side, needing the plenum removed, replace all 3 when you are there (keep and label the working spares). If it is on the passenger side and easy to get to, just replace the faulty one. Regardless, make sure to replace both O-rings for each injector, and lube them (and the socket) with a little gas before you install to make sure they slide and don't get pinched.

txpath4x4 Posted November 17, 2015 Author Share Posted November 17, 2015 Thanks, and I have one out on each bank so I figure I'll do them all. And thanks for the heads up about the gas and the O rings Link to comment Share on other sites More sharing options...
txpath4x4 Posted December 11, 2015 Author Share Posted December 11, 2015 Hey peeps, replaced all injectors and the pressure regulator. Now I got a stutter and some intermediate missing at idle. But if I nail the throttle it runs ok-ish... Any suggestions? Link to comment Share on other sites More sharing options...
Kingman Posted December 11, 2015 Share Posted December 11, 2015 I'd start by making sure there are no vacuum leaks Link to comment Share on other sites More sharing options...
