Two unrelated issues? Check your battery?

Gotcha, yeah mine looked pretty poor but I just cleaned it all up and even with the rotted out brackets/ grounding strap mine still fires right up and runs every day. Might test the coil? 87 XE red/red 3+3+33's=my finder

Think that grounding strap is for the coil, mine was in similar shape and I was having similar issues. Replaced the coil and it seemed to solve the problem... The thing circled in red is the ignition control module. How long does it run before it craps out, when I was dealing with it it would stop giving me spark after the truck heated up. 87 XE red/red 3+3+33's=my finder

Check for corrosion on maf and injector plugs, could also be a wiring issue. 87 XE red/red 3+3+33's=my finder

Did it throw any codes? Also worthlooking at the wiring and harnesses for the injectors (MAF wiring as well). 87 XE red/red 3+3+33's=my finder

Problem may not be injector, have you checked codes yet? That rev limit is limp mode, I have had that happen and had issues other than injectors. 87 XE red/red 3+3+33's=my finder

I use rough country UCA's I like them, and they come with grease fittings. (Fought urges to not make a BJ angle joke...) 87 XE red/red 3+3+33's=my finder

As long as the old belt is intact you will be able to just do a new timing belt as long as you follow the instructions and get things lined up/count teeth and set the tensioner correctly you should be good to go. It is easy as long as internals are not jacked up via broken belt etc. Sent from my PC36100 using Tapatalk 2

Wow thats low!

Ran it through DEQ/smog... and it PASSED! Six Months of tinkering and troubleshooting in my free time pays off!

Zombie'ish thread update... haha... Anyways I cut the flanges off the old cat and made an extension that just bolted up to cover the difference. Not pretty but it works fine.

Fabricated an extension for my "bolt on" catalytic converter using the flanges from the old cat. Installed it all, now to see if it will smog. Oh and adjusted timing to spec.

I second those checks, especially checking codes, sounds like limp mode+ something else.

Is the cold idle part about where it should be?

^^^this^^^ see the maf cleaning sticky for more info. Sound like limp mode, will it go past 3000?

It actually warms up quickly regardless of weather for me just a few minutes at idle or driving. Idle specs are different manual and autos as well.

Just curious about what the cold idle speed is supposed to be, i.e. right after startup until the fast idle cam is in position? Mine is steady at 2000 or so then dropping to about 900, which is close enough to the 800 that is should be for me when warm.

End up resolving the issue?

Cleaned TPS harness connections clearing that code, put it back together and hot a maf code, cleaned the maf and connections and did the good old wire Jiggle and now it is back to running great.

Mixture is all computer controlled, checked for codes would be tour beat place to start.

Very nice!

There is a temp sensor and a temp sensor. The sensor will not affect the guage if I recall correctly. Where was the one you replaced? Front of the block on the driver side behind the timing cover?

Yes, the ignition coil can produce that issue too, recently replaced mine for that reason.
