Great job!

Ian before the goes up there he needs to get me parts to get mine to pass.
 
I found my air injection pipes and valves for $90. :yelclap:

I need to start a list of things that I actually want to do to mine and buying parts. I've focused so much on Jennifer's that I've ignored the poor '86. I took her out the other day and had a blast. For whatever reason the '86 is much more fun to drive than the '91...perhaps because the '86 is mine to break and I don't have to feel guilty if I do!

Perhaps i can send money Merlin's way have him obtain parts for me. I'm not even asking that he gets them for me at his discount, but it appears that stuff is cheaper down there than up here (based on the prices he quoted in his post for the ZJ tie rod upgrade). :repair:

Hell, if I can get enough stuff down there to save enough for the gas it will cost me to get there it would be worth the trip!

THere seems to be different tests used in Texas, at least here in Harris county.

The 89, 121,000 on the odo, recently replaced the head gasket, this one gets exceptional mileage, so far 17 in the city mixed, 24 highway before the head job, 2 WD had the following results using the ASM, actual load test, test.

standard @ high speed ...................................low speed
HC (ppm)189...............mine was 123 .................194..............mine 30
CO% 2.36...................mine was .44 ................1.74...............mine .44
CO2 % N/A.................mine was 14.2 .................N/A...............mine 14.2 NOx(ppm)..1233............mine 0.0........................1340............mine 0.0
O2 % N/A...................mine was 0.0 ...............N/A..............mine 0.0
Dilution......<6...............Mine 14.6....................>6..............mine 14.6

Then my 87 4x4 which is not load tested here (they won't run 4X4's on the dyno here for some reason), but it was tail pipe sniff tested using a "2 speed idle test", and this has lower MPGs than the 89 (10-17), about 35% lower, 256,000 on the odo, had:

standard @ high speed ...................................low speed
HC (ppm)220...............mine was 8 .................220..............mine 28
CO% 1.2...................mine was .04 ................1.20...............mine .13
CO2 % N/A.................mine was 14.9 .................N/A...............mine 14.7 NOx(ppm)..1233............mine 0.0........................1340............mine 0.0
O2 % N/A...................mine was 5.1 ...............N/A..............mine 5.4
Dilution......<6...............Mine 14.9....................>6..............mine 14.8

I would like to see more data on other's test results and how they compare to other preformance issues. I am starting an OEM thread on this hoping to get lots of real data posts nation wide.

I found the NOx and O2 data between data sets particularly note worthy as wel as the huge limits for CO compared our actual test results.

If ya wanna see my failed results, I have them.

It was kinda strange actually, the more parts I replaced, the worse the numbers got in some areas.

Hell yes, the more bizzare the data the more intersting, and possibly more revealing. Failed data actualy may be more interesting, especially if it has repair history that fixed it someday as a folow up.
 
I FINALLY found my emissions testing results. :yelclap:

"rebuilt carb" ??? What engine, year....? Did it ever pass?

O2 sensor?????
 
Oh, sorry, that's for the '86 with the 2.8L...there is no O2 sensor for it.

Nope, it still hasn't passed. The air induction pipes and valves are missing......still.

I've spent the better part of a year trying to decide what I want to do with it. V8 conversion....3.4L V6 conversion.....rebuild the 2.8L......bring it back to street duty....make a trail rig out of it.....Jennifer and I have really considered making a rolling bar out of it and just taking it to club events. :cheers:

Sadly, we have put more thought and effort into the bar concept than actually doing anything with the rig. We might have to do an XJ trailer for it too so that we have enough room for all the alcohol. :skull1::skull1::skull1:

So it's not even TBI, just a carb? Was it one or two barrel carb? Did you ever try replacing the carburator and some its vacuum valve junk? 2.8 L was V-6, or ????? Sounded like a carb problem to me.
 
Yep, it's the 2.8L V6....2 barrel Varajet Carb...nope, never tried replacing the carb, but did rebuild it. Vacuum isn't the problem. The lack of air induction parts is. There is an air pump that sends air into the exhaust or intake depending on engine temp. etc. The previous owner removed the pipes and valves.

The little rig runs great otherwise!
