Rebel526 Posted April 17, 2012 Share Posted April 17, 2012 OK, here's what I have done...Though I have NO idea how I screwed something up! I changed my oil and spark plugs.....THAT'S IT! I start the truck, watch oil light go out, shut down. Replaced breather cover. Started truck and began to back out of shop.....truck dies. I'm thinking "HUH?" Start up again & notice it sounds a little off. Give it a goose and watch the tach....it goes up to ~2700- and sputters! I think "Uh oh, limp mode...WTH?" slide passenger seat forward and set computer to diag and check codes..."23" & "45". My list shows these to be: 23: Idle Switch; 45: Injector Leak What in the world could I have done to create THIS??? Ideas? Link to comment Share on other sites More sharing options...
Rebel526 Posted April 17, 2012 Author Share Posted April 17, 2012 EDIT:: I goofed...Codes are: 11 12 13 33 I know about 33, that O2 sensor doesn't even exist. But the rest? I've checked wiring, nothing seems amiss... At a loss here.... Link to comment Share on other sites More sharing options...
Alkorahil Posted April 17, 2012 Share Posted April 17, 2012 11 Crank Angle Sensor/Camshaft Position Sensor. 12 Air Flow Meter/Mass Air Flow Sensor. 13 Engine Coolant Temperature Sensor. 33 Heated Oxygen Sensor. Its almost like you unplugged a harness by accident and didnt realize it..... Did you have the battery disconnected while doing this work? Did the CEL come on as soon as you started it up? 1 Link to comment Share on other sites More sharing options...
WarthogWD21 Posted April 17, 2012 Share Posted April 17, 2012 check the distributor, there are two wires that go to it, if one is unplugged it will make the Crank Angle Sensor/Camshaft Position Sensor go off and throw off your engine. 1 Link to comment Share on other sites More sharing options...
nismothunder Posted April 18, 2012 Share Posted April 18, 2012 Didnt he just remove the dizzy? Link to comment Share on other sites More sharing options...
Rebel526 Posted April 18, 2012 Author Share Posted April 18, 2012 Thanks for the replies! Not sure what the deal was...I wound up swapping the dizzy...found that one wire to the coolant temp sensor was broken at the plug (cut off plug and used spade connectors), unplugged/plugged in EVERY connection I could find. I'm guessing it was a bad connection SOMEWHERE as the problem went away and its running great again My CEL has never worked, I just know to check the ECM when it's not running right Link to comment Share on other sites More sharing options...
adamzan Posted April 19, 2012 Share Posted April 19, 2012 It will run even better with an o2 sensor! Link to comment Share on other sites More sharing options...
BuckRyp Posted April 23, 2012 Share Posted April 23, 2012 i need to gt an O2 sensor mine is just cut off. Link to comment Share on other sites More sharing options...
Rebel526 Posted May 5, 2012 Author Share Posted May 5, 2012 It will run even better with an o2 sensor! The previous owner had the hole welded in and cut the O2 sensor off (instead of simply unplugging it ) I'll get that corrected when I can, funds are a bit short at the moment Link to comment Share on other sites More sharing options...

Kingman Posted May 8, 2012 Share Posted May 8, 2012 87s shouldn't have a CEL? The TBI trucks run just fine without an O2 sensor, they're only used above 2,800RPM for cruising. Link to comment Share on other sites More sharing options...
