New Toy 1986 Jeep Wagoneer XJ 2.8 PICs Added 9/24/2013

Post by **fool4fish1226** » 22 Sep 2013, 10:10

Ok first I will start this post with saying that this is the only site I am a member of because of the type of people here - gotta love TINBOATS

I am looking for a map sensor for my new toy and having no luck (locally or Web). I have purchase 2 so far, both of which were wrong do to the pin configuration. I was hoping that there maybe some jeep heads on here that could point me in the right direction. I know pics would help but my camera is at work and will post some this coming week.

I guess I should tell you why I believe it to be the map sensor. The jeep starts and idles fine but when giving it throttle it hesitates real bad (almost wants to stall). I have changed wires, plugs, cap, rotor, etc. Any help would would be greatly appreciated.

Haters welcome I know the 2.8 is a problematic engine, future plans to do a 3.4 tricked which will be straight carb no ecm, limited electronics, and vacuum (vacuum operated 4x4 selec trac) but till then I want to play with it.

Thanks Tinners

Welcome to the world of Jeep, ('99 sport, 4.0, 2wd, 5speed).

Thanks Jerry hope is well. This is the problem I am having the sensor you found is what seems to be list for my jeep but the pin configuration is off. The grooves on the one you found the pin grooves are on the first and third posts and mine are one the first and second first one is at three o'clock and the second one is at 12 o'clock. This has been driving me crazy. I will post pics on tuesday to help everyone out.

Been out fishing lately? I have not, been gator, pig, and deer hunting should get back on the water sometime in november plus "A little Snookerd" is most likely getting a overhaul too, gonna replace all the wood with aluminum.

Thanks again

Thanks S&M! not sure changing the plug will help? It may just confuss the ECM any thoughts?

Had a tournament Wednesday and got skunked. I did manage a Puffer Fish (the tournament mystery fish) which would
have been good for a door prize and a mystery fish pennant, but mine was second. I should have re inflated it,
and put it back on the scale

Here is the link to the website I maintain for the club. https://www.naturecoastanglers.com/
Go to the BRAGGIN BOARD for photos. Clicking on the photo will get a bigger pic.
I'm on the first page holding my poor little puffer.

Have you checked the serial number on your engine for the correct year and Model?
The engine may have been replaced with a newer one.
I will take another look when you get the pics up.

Maybe check for any vacuum leaks? Can you slowly increase throttle without it stalling? Even tiny leaks will cause big problems. Good luck.

I have been searching for leaks - this thing is a vacuum nightmare!

Changing the plug should allow you to use the newer type of MAP sensor. Should not confuse the ECM,as long as the wires are in the right place you should have no problems. That sort of thing happens when the manufacturer changes the part in mid model year. If there are more of one type on the road, the aftermarket follows the most popular type and discontinues the other. Therefore,in your case not being able to find a MAP sensor with your plug configuration, you have to change the plug to accomodate the other style port. I hope I haven't been too confusing.

Thanks S&M I am going to give it a try and see what happens. I will let everyone know.

That looks like a GM 3bar MAP for a 2.8 '86 Buick Regal.

Also found a good link for dynamic testing a MAP with a volt meter.

How much lift you got on that DAWG?
Looks like I'll have to get a lift kit for mine.
