I asked Chad at Golen engines about the differences. He said you can't tell the difference in a built stroker.

Super rich generally leads to the MAP sensor and/or it's vacuum source being wonky.

Stay away from the Cardone crap.

I got my first truck at 15 and it was a project for me and Dad. I learned alot. Suggestion. Begin with Tip 1 and continue on to 5. 5 will tell you if 6 is needed. If the CPS is coming off again or a new one needed to go on again, do the drill mod. Tip 27 will help develop soldering skills along with logic and organization skills for your son. any questions, post 'em up!!!

Yup. The auto ones are more plentiful and work just great.

You'll get it figured out.

Comes with 2 connectors. You only use one.

See Post 8 in my Tips and save a boatload of $$. I've read it 10 times. Are you saying it could be just out of adjustment? Or I will be able to see that it's bad before I buy a new one? I'm confused. You need to hone your reading skills I guess. "For those with a MANUAL TRANSMISSION--the TPS for the manual transmission XJs is stupid expensive. You can substitute the automatic transmission TPS which is reasonably priced. The square 4 wire connector is just not used."

See Post 8 in my Tips and save a boatload of $$.

Why $130?

Yup. Always set the TPS on the Engine side.

Does anyone have an 88 to 90 TCU laying around? I wanna ditch the OE one in my 87 MJ.

This opens up a new world in oil filters for your Renix. http://cruiser54.com/?p=257

What's a Honda style automotive relay? Got any specs? 4 pins. It's also used on some American stuff. BW4136. http://www.oreillyauto.com/site/c/detail/BWD0/R4136.oap?pt=01646&ppt=C0094

Test your CPS output per tip 7.

BW 4136 relay available almost anywhere. If you make good ground connections and mount the relays so they can't take in moisture, you'll be just fine.

No need to flip it.

The tune up parts you're mentioning should be replaced with the plugs every 30,000 miles.

I can't say for sure I have no Vacuum leaks as my current brake booster may be a culprit for mine, but I attribute that leak with a different issue it has, and it only happens when I first touch the brake pedal. It's supposed to be nice this weekend, so I plan on removing and cleaning off the CPS. I may trace and go over the ignition wiring in the harness and if I have the time to eliminate the C101. Plan on 2 hours for the c101 elimination and take your time!!

Rotella T3 and Wix filter. Check all fluid levels and conditions. Grease every nipple on the truck and get a good gander under there.

Grab 89 to 90 ECUs and 88 to 90 TCUs. I need a 1988 or later TCU...........

Did you screw up the vacuum line to the MAP sensor on the firewall during this fix?

That one looks good.

With a factory stat, at 20*F outside, I have cabin heat in less than 3 miles of driving.

Is the injector harness rubbing on the rearmost head bolt?
