Apparently he's a pretty good shot :thumbs: Seriously though,glad he's OK :thumbs:

Good news that it's running good again.When replacing to vacuum hose to the MAP sensor get a little extra,never know when those plastic lines going to the idle speed control solehnoid & throttle kicker are gonna break(those are the small tubes going to the base of the TBI. Also,timing is 4*...

Good idea if you don't know how old it is. The program I use is Tuner Pro RT and is free.It can be a little tough to use at first.You Tube has many videos on learning how to use it.I'm still learning after a year and a half and has helped me diagnose a few problems with my burb in that year and...

Great idea Jim :thumbs: And here's how to do it 4QvR5Nqun4g

I'm assuming you mean connect a laptop to the OBD1 port? Sure,here's a vid of mine... zXyEqKlzQjI Do a search on YT,look for GM TBI

Try switching the injector connectors and see if the cone pattern goes to the opposite injector.This should tell you if your injectors are ok. It's possible the ignition module in the distributor is going bad also. I was thinking if you lived in SoCal we could meet and I could use my...

Sitting here thinking,a shot in the dark.....unplug and remove the EGR valve.Clean as much of the built up carbon off of the valve and the opening on the intake manifold where it bolts to.Have a vacuum handy to suck all the loose carbon from the intake.You may have to buy a new gasket.Brake...

What does the injector spray pattern look like? Is it a nice upside down cone?When snapping the throttle does it shoot a lot more fuel while still maintaining the cone? What I'm trying to do is get an idea of how good your fuel pressure is,how good the injectors are and how good the fuel...

First off welcome to TMC :thumbs: Could you explain this '' when I floor the truck all it does it scream and barely moved'' a little better? Does the vacuum line from the map sensor go to a ''t'' where it connects to two intake runners? When cold and when it's first started does the idle...

3.53 for regular at Sams Club & Costco,always the lowest.

Happened to my daughter's Expedition.She junked it.

Nice work & write up :thumbs:

That's awesome but I hope they put a scatter shield over the transfer case :thumbs:

I like it,nice stance :thumbs:

:drool:

She used the washer yesterday and was happy :D No threat of grumpiness now :thumbs:

Yep,didn't want Grumpy to get too grumpy :lol:

On Grumpy's burb,a couple of things... Replaced the starter Got the windshield washer working Got the rear hatch window washer working Rain on the way,thought it would be nice if they worked :)

Checking the miles per gallon on my burb is a waste of time,I know it's not good.On the other hand my neighbor recently bought a Priius,I told her the gas she saves means I have more to burn......she shook her head :lol:

OK then.......... SAM'S Club & Costco 3.59 for 87 Chevron 3.73 for 87

Your check engine light is on,something wrong? :jester:
