blownbimer Posted February 17, 2006 Share Posted February 17, 2006 Well, i thought she was running good....aparently not. I took her over to the emissions place, and she failed the CO part of the test.100 on the co with a limit of 20. Looking at the papers, it failed at high speed on the dyno...so Its over fueling then. Where to start checking? this car has recently had a tune up, but the timing hasnt been set b/c of no marks. 02 sensor? where oh where to start?

ShawnW Posted February 17, 2006 Share Posted February 17, 2006 Start at the timing. Theres a marker thats supposed to be on the crank pulley area. It may have been removed or its so covered in oil you dont notice it. Link to comment Share on other sites More sharing options...
blownbimer Posted February 17, 2006 Author Share Posted February 17, 2006 That plastic peice is GONE on this one...motor is super clean on this car, so its not just hiding from me.

Prob play around with it...or go to sidewinder and get one...are they a PIA to put on? its a steel thing, botlts on on top of the water pump, using two of the wp bolts. They're easy to put on with the engine on a bench, maybe harder with it in the car.... Link to comment Share on other sites More sharing options...
blownbimer Posted February 17, 2006 Author Share Posted February 17, 2006 Guy I got it from just replaced the water pump...humm...sounds like I need to call him and see if he still has the marker Thanks Erik Link to comment Share on other sites More sharing options...
blownbimer Posted February 17, 2006 Author Share Posted February 17, 2006 Anyway to adjust the mixture on this one? or is it all electronic? Thanks Erik Link to comment Share on other sites More sharing options...

Thanks Erik Check that it goes into closed loop.... once it (the o2 sensor) warms up the light on the ecs should flash quickly. Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted February 17, 2006 Share Posted February 17, 2006 Did you check your muffler bearings?That may be the problem.Maybe blowing oil back in through the knueter valve due to rapid expansion. Just kidding.Possible that one of the injectors is sticking a little.Not real familiar with the "T" ea81's.Also the idea of the 02 sensor may be a good place to start.Let me know if you would like some extra help.

blownbimer Posted February 18, 2006 Author Share Posted February 18, 2006 temp gauge never moves much, maybe the thermostat is stuck open, and not letting the car warm up...it has been like 5 degrees here..heh Thanks Erik Link to comment Share on other sites More sharing options...
