Frankzao Posted June 30, 2012 Report Share Posted June 30, 2012 I first tested my 2.3L back on 05/05/2012 and it failed both the 15mph and 25mph for HydroCarbons. So after replacing my 2 year old spark plugs and recharging the K&N air filter, I had my Milly retested.. here were the results: So I am left with where to go from here......the only thing I can think of is that I need to fix my leaky valve cover.....the oil leaks so bad that it causes a random miss fire on cylinder #3. Thoughts? Quote Link to comment Share on other sites More sharing options...
enginph Posted June 30, 2012 Report Share Posted June 30, 2012 I didnt test after changing the injectors but looking at the power and mpg gains I am likely to pass. Wait for my result and then clean the injectors. I bought a used set off ebay, sent them for cleaning and swap my old ones with cleaned ones. I have my used set if you wanna do as I do. Or you can send your set and wait a week. Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted July 1, 2012 Report Share Posted July 1, 2012 I doubt a leaking VC could cause that much, maybe your just in CA and thee stupid hippies. I think those results may pass in VA spark plugs, filter, and of course coils which I think you replaced awhile ago correct? No CEL's?

I replaced everything and failed again and again in HCs just like him. And I know anyhere person here who failed with a high mileage MCE. I think this is generic to 2.3L.

///BHRpowered Posted July 2, 2012 Report Share Posted July 2, 2012 Well clearly there is another cause as from the factory when everything was new they had no problems, now I fully intend on removing the precats, but if you replaced the injectors, coils, plugs, and o2 sensors etc then you should have no problem, nothing more. Your at the limit at 25mph but much higher @ 15mph so that tells me its something relating to low spark. Quote Link to comment Share on other sites More sharing options...
Frankzao Posted July 15, 2012 Author Report Share Posted July 15, 2012 Well my Valve Cover Gaskets are being replaced.......will run a retest after to see if the hesitation and HCs go down. Quote Link to comment Share on other sites More sharing options...
Frankzao Posted July 15, 2012 Author Report Share Posted July 15, 2012 Here's the results from 05/2012 before the new plugs..... Then after the plugs in 06/2012.... So the question is, will the VCGs lower the HydroCarbons enough? Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted July 16, 2012 Report Share Posted July 16, 2012 Im suprised the plugs made that big a difference, how many miles were on them/type? I go 30k on millenia plugs with NGK platinums. Changed plugs on the Jeep today, after 58k the electrodes were pretty worn down and the gap almost .58. Towing and offroading really took a toll. VCG shouldn't lower anything, there not letting anything in, jsut letting some oil out - but you should do it if there leaking anyway. Estimated 1-2 days work, do all the vacuum lines at the same time as well. Have you done anything with pcv valve? Quote Link to comment Share on other sites More sharing options...
Frankzao Posted July 16, 2012 Author Report Share Posted July 16, 2012 the VCGs are needed. Cylinder 3 swims in oil as well as a little in 5.....the 2 year old plugs had 25000 miles on them... I've done nothing to the pcv valve.... vacuum lines were switched a few years back tp silicone and they are still perfect..... Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted July 16, 2012 Report Share Posted July 16, 2012 silicone vacuum tubes - excellent choice. The design of the VCG is a bit weird the way the plugs are isolated and then gaskets around them. If swimming in oil you should change them anyway. It can't hurt your emissions Quote Link to comment Share on other sites More sharing options...
enginph Posted July 17, 2012 Report Share Posted July 17, 2012 I have the same, couple coils were swimming. I changed PCV at 120k or so. My recent smog report, before injector cleaning: Quote Link to comment Share on other sites More sharing options...
Frankzao Posted July 19, 2012 Author Report Share Posted July 19, 2012 what kind of plugs do you have in there? when did you replace them and the oil? do you have a misfire? My misfire causes the car to really hesitate Quote Link to comment Share on other sites More sharing options...

Frankzao Posted August 3, 2012 Author Report Share Posted August 3, 2012 both my front and rear cats were destroyed. They fell apart.....clogged.....I think this is a good thing...replacing the cats.....its just gonna be $$$$$$$ Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted August 4, 2012 Report Share Posted August 4, 2012 My suggestion - remove the precats, hollow them out, hell just disconnect the pipe, cram a stick in and run the engine to clear it all out, then get a better aftermarket main cat Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted August 5, 2012 Report Share Posted August 5, 2012 VA hasn't done actual tests in years,sometime in 2005 they switched to obd reader only. No codes and you pass. I would have to dig but may be able to find results from 2002 and maybe 2001 Quote Link to comment Share on other sites More sharing options...
