Think so to. I want to say 39 PSI. But not sure. That number sticks in my head cause my '00 is 49 PSI.
And I always wondered why the difference between the years.

yea i figured 20 PSI was a little lower than normal. Also thanks!

Changed the TPS today and it is still misfiring and bogging down. Maybe the computer has to relearn the specs of the car. May need a new fuel pressure regulator is the pressure is low.

I just got in my car to move it. Start it and let it idle like usual. I go into reverse and it dies. Like usual. I restart it and then put it into drive and when i hit the gas pedal it doesnt move and starts misfiring. Eventually it surges forward and i press the gas a little harder. It misfires once more so I put it in park and lift the hood while it is running. I push the throttle cable a little bit and it misfires again. Then the engine about stalls out and jumps back to life. Along with thick white smoke coming out of the throttle body. I turned it off and let the smoke clear. Started again and it still idles well. Car is throwing a code 22 now. I'm about ready to sell it(as much as I don't want to) and find another car because i need a DD and i don't have the money to keep fixing things on here. I did order a fuel pressure regulator because my neighbor has been a mechanic for 50+ years and he said that is the most likely culprit.

From what I read the white smoke is just a missparked plug. Car runs fine now. Still got that problem. Fuel pressure regulator should be here in a few days.

White smoke can be a lot of things. Can’t say I’ve ever heard of a “missparked” plug. Fouled plug?

Cordless telephone

im thinking maybe it sparked at the incorrect time. I couldn't really find anything else on the topic so it could be anything.

I eventually want to do an EV conversion on this jeep WAY down the road. Mainly because of financial reasons and the fact that i don't know the full extent of the rust damage on the vehicle.(probably not much). What are your thoughts?

I've looked into it for my Wrangler after seeing some electric CJ7s on YouTube. I'm hoping maybe in a few years, the cost of used batteries will drop as more evs hit the junkyards and are more widely available.

Cordless telephone

the more mainstream it becomes, hopefully it gets cheaper. There are a couple cherokee conversions on YouTube but never explain the cost or how they did it.

An EV conversion to a Jeep is an interesting concept. I am not sure how practical it would be for a XJ or for many existing vehicles for that matter. It seems like a lot of effort and trial and error unless a thoroughly proven kit comes out and I expect that would be very expensive. Using salvaged battery packs likely would be disappointing.

Considerations include the weight of the battery pack. That depends on range but typical battery packs today range from around 500 pounds to over 1500 pounds. Of course you lose the weight of engine and transmission if you do away with those completely. Then add back weight of battery mounting structure and body reinforcements, electric motor(s), power electronics and wiring. The XJ does not have a huge payload capacity due in part to unibody construction. It is somewhere around 1100 pounds (?) total including driver, passenger and gear.

The electronics for power conversion is complex. The battery pack and electronics typically need cooling which adds to the complexity. Then figure out suitable cabin heating and cooling if you want a few comfort features.

I recently was fortunate to drive a production version of the Audi all electric e-tron 55 quattro SUV and see a standalone battery pack. The battery module is massive with dimensions a bit over 5’ x 7’ and about 13 inches tall. It is air cooled and liquid cooled with antifreeze and a chiller for high temperature operation. The battery pack bolts to the underside of the body with 30+ bolts. Weight is in the range of 1500 lbs. With this size battery pack the range is 200+ miles.

Performance is very impressive. I drove it after it had set out all night in below freezing temperature with less than a full charge. You would not have known that from how it performed. Cabin heating and heated seats seemed no different from a standard vehicle. With the all-wheel drive quattro system snow and ice driving performance was fantastic. It was an impressive view of where mainstream electric vehicles are headed.

So I bypassed the ballast resistor and now the thing acts fine. Goes 75 without a problem. I guess that was the problem. Still testing to see.

Interesting and something to keep in mind. Someone remind me what that resistor does. Is it on the fuel pump power circuit?

Cordless telephone

it lowers the voltage to the pump. Making it quiet.

There is a shop nearby that has a cherokee laredo sitting. The entire body is rusted to hell but it has all the chrome I want to put on mine.(grill, handles, wood grain dash bezel, etc..) Gonna go ask them if they want to sell it and clear space in their lot and use it as a parts car. I wanted a laredo originally because of those features but couldn't find one for sale.
