I have been lurking on the forums absorbing the collective wisdom on the forum.
I have a 89 Renix era XJ 4.0 engine, AW4 Transmission, D30 front w/ disconnect axle, and Dana 35 rear. 141000 miles.
The vehicle has a ton of sentimental value to me and I have started the process of getting her back on the road. She has been in storage for 15 years, I parked her when the Ignition Control Module went bad, and I didn't have time to sort it out.
About a year ago I went through the basics, replaced the fuel pump, filter, injectors, and all associated o-rings, fuel pressure regulator. Plugs, cap, rotor. and battery. I did the brakes, front and rear. Put new tires on it, and replaced hoses, serpentine, air filter etc. I had a little trouble getting a spark, but eventually tracked it down to a bad connection between the coil and the new ICM. Low and behold she fired up.
At idle she sounds great, and revs, without issues. In drive she lacks power it almost feels like the transmission is slipping badly. I drove her a mile or two but she barely made it up an small hill outside the house. Right before I parked her she was driving fine.
Questions: Any suggestion as to what could be causing the severe lack of power/slipping?
Has anyone else had these types of symptoms after storing their vehicle?
Can transmission go bad simply with storage?
Any other service items that I should be concerned about?
Thanks guys.
