Any way I have a new question pertaining to my 90 Silverado 350 5spd.Has anyone had any experience with a lopey idle perf cam not being compatible with the map sensor on this throttle body engine?
it could be your ring and pinion,(differential), i had that problem with my 93 chevy 1500. mine went out on me. if it starts making a winding, or a siren noise, then it is your rear end.
At this point i decided to go for the basics , its eather fuel or fire so i replaced my fuel filter and since i didnt have a fuel pressure gauge i placed one in line where the filter normally went, The pressure read 20 when you first turn the key on the 65 when you started the truck , if you stomped the gas and the truck died the pressure never dropped from 65 so i figured thats not my problem. Additionally the whole fuel system was eitehr replaced or flushed by the dealership around 10k ago so i really didnt think it was my problem but hey i checked it anyway. I also changed my tps becuase i got a trouble code from it but it turns out i caused that trouble code by having it unplugged when i started it once ( oops ) Then someone on the web mentioned the MAF sensor might be dirty so i took it out and cleaned it which it really didnt seem to need it ( looked clean and shiny )
Next i changed my distributor cap and button even though they too didnt look like they needed it. I noticed when i changed them that the distributor was loose so i thought maybe that was my problem. I adjusted it back and forth and i got no change so i got online and read that i needed to get the engine to tdc and line the button up with the number 8 molded into the base of the distributor ( not the number 8 contact but the number 8 on the base of the distributor cap ) I lined it up and locked down the loose hold down clamp and still no luck. The truck runs like absolute crap, it idles pretty good but as soon as you put it under load like shifting it into reverse it dies. If you step on the gas fast it dies, if you real slowly give it gas it will rev up in park allmost like normal but you have to be real slow on the gas pedal. Anyone have any ideas? Ive gotten to the point ive told my neighbor to look out for the flaming truck rolling down the hill towards his house because i feel like setting this thing on fire.
Would love to find the problem quick!
The current problem is that the truck keeps losing power (it has only stalled out once so far) - he cannot seem to go past 25 mph. When the engine temperature reaches 220 to 230, the vehicle will start backfiring when the accelerator is taken past one quarter open throttle (when he pushes the accelator more than 1/4 of the way down, the truck starts backfiring and losing power; the more he pushes down, the worse the backfiring gets).
So far he's been able to deal with this by pulling the truck off the road and allowing the engine to cool off for anywhere up to an hour.
Considering that he has over 1500 miles to go, I'm trying to find a fix that will at least get him home (and we can take a more in-depth look then).
Any ideas?
The hazards all work, blinkers, running lights. All of it. No bulbs are burnt out, and no fuses gone. I also changed by brake switch, And no luck there.
It would be appreciated

i have a 94 Chevy 1500 Silverado and my speedometer and tach are not working but my battery, gas, oil pressure and the other gauges work, does anyone have any ideas to fix this problem
thanks Aaron
Now I'm assuming you're talking about the small cable on the pedal side? I'd have to look that up in the shop manual. If I can find the thing somewhere around here. Is that the cable that you're referring to?
When I bought the truck the horn didn't work, the 4x4 light on the sterring wheel dash and tow light do not come on. I did look at the owners manuel and did figure out the horn problem. I changed the fuse and it works great. Does anyone know where or what fuse the tow light anf 4x4 fuse are. I tested it out and they both work. I took the pick up off roading and the 4x4 worked great. It is a 4x4 on the fly. It s on the left of the sterring where dash. That works great but I can't get the town lights or 4x4 light to work on the dash....Please help.........
Did you resolve your problem? My 2001 Siverado 5.3L started doing the same thing today. I've got 58,000 miles and after it has sat for 30mn or more, it takes several seconds to start, but once it's been running, you can shut it off and it will start right up. I was thinking leak in the line, causing it to lose pressure, but advancing the key for several seconds before starting didn't seem to have any impact on the slow start.
Hoping you've got some light to shed on the subject...
Thanks,
Steve
