I just bought a digital tach from eBay, once i hook it up i will do the base idle adjustment and see what happens. I was going to buy a aldl cable but the manufacturer never got back to me on my...

So any aftermarket tach will work? I would like a digital one instead of needle that way i get he most accurate number

Is there a way for me to read my rpm’s digitally while doing this? I can’t use my scanner because when it’s in diag mode the rpm’s fluctuate. And i don’t really trust the factory gauge.

Ok yes this makes sense, so as of right now it looks like i have to adjust the base idle with the IAC unplugged and then see what it does after it’s plugged back in. I mean unless you have another...

Sorry i don’t think I’m understanding what your saying, your saying if it stays at 600
My scanner is lying to me? Can you please elaborate? How would it stay at 600 if once i plug in the IAC it...

I had the whole dash harness out of the truck and i did not noticed any cut or spliced wiring or any switches, i don’t think the issue is in the wiring to be honest, the computer in the truck is a...

That makes sense but if the wires were shorted together wouldn’t they cause the SES light to constantly flash also aren’t those the pins that you jump to get the IAC to go fully closed?

I don’t have a multi meter to get resistance, what wouid that do anyway?

You are essentially tell me to adjust the base idle speed manually lol

OK so I installed the new chip in the computer today and I did not notice any difference in the idle speed or the way the truck ran or drove. I didn’t notice any difference the RPM needle still sits...

Ok i get what your saying, i won’t be able to install the new chip
Until Monday evening but I’ll let you know what happens. I really don’t think it’s the chip i think it’s something to do with the...

Hi i received the new prom chip on Monday but i have not had time to install it yet. Wheather been shitty, i will probably install it this Saturday. One thing i was thinking about the other day is if...

i made the purchase, i should have my new prom chip by next weekend, fingeres crossed this fixes my issues.

i will let him know, hes mechanically inclined but hes old school he likes carbs, he doesnt really like dealing with anything that has a computer

Cool, i was looking at getting the BIN for BDUY burned since it’s the newest BIN with the same mask as mine that i was able to find on this website, i wanted the BIN for a 95 but it wasn’t available...

I see, i don’t think my neighbor cares to install one, he just wants to fix his truck. It’s probably his 02 sensor honestly

Ralmo94, when i order my new prom chip should i send him the bin file for my truck or send him the bin file for a 95 silverado with a 5.7 and 5speed? The computers are the same as far as the 7747...

Exactly! I was surprised that was even showing up on my scanner

Ok I’ll let him know. I realized that earlier to suggest the pcm swap. Sorry for asking that question. I found a guy on eBay that can burn me a new prom chip but i have to send him the BIN file....

I see, would i be able to put a 7427 in my truck? Where would i be able to get a prom? My truck has a reman computer in it but i opened it up and the BCC code is correct for my truck but I’m
Not...

He rebuilt the throttle body not to long ago but he used a stock rebuild kit so the fuel diagram is not messed it, also truck has a new fuel pump. O2 has not been changed, truck sat for years before...

So I hooked up my scanner to my neighbors truck, which is a 94 with a 5.7 L with a 4l80e transmission and not only does my scanner show a lot more information on his truck, but I was also able to...

I agree, I’ll sell my 2018 Silverado before i ever sell my 93, there just so well built, reliable, easy to
Work on and parts are cheap. Just sucks that there a bit hard to diagnose since they are...

No it doesn’t sometimes it shows drive/reverse and other times it shows p/n this does not change with clutch depressed or brake pedal depressed. It’s just randomly shows something each time i plug it...
