    88 5.7 low on power

    well today i adjusted the timing to about 3 degrees advance and it seems to have helped my low power issue a little bit. But whats not helping my low power issue is the fact that it's still missing. It doesn't seem like the mis fire is rpm based due to the fact that it does it from idle to 4k...

    88 5.7 low on power

    I was referring mainly to low power I havnt been able to drive it enough to see if it’s surging (I would quote ur message but my phone doesn’t like me). when I advance it, what values should I see?

    88 5.7 low on power

    Well I bit the bullet and bought and installed an o2 sensor. I dont think I’m having the missing issue anymore. So schurkey, you were right. We are just back to having my original issue from my first post. I read somewhere that setting the base timing to 3 degrees advance helps with power and...

    88 5.7 low on power

    Would 4-6 cross counts within a 10 second span at idle be ok? I haven’t tried at higher rpm’s yet.

    88 5.7 low on power

    after calling people I know all weekend, I have a scan tool that works. now my issue is i don’t know what any of this means. the only thing I find kinda weird is that at about 1300-1500 rpm (which is where it runs the worst) my o2 sensor jumps from about 150 mV to 800+ mV and then back down to...

    88 5.7 low on power

    ok, I have been driving my truck daily since my last post and it’s gotten worse. The thing has no power and it runs rough. It sounds like it’s missing esspecially at partial throttle. When you are at the same throttle position cruising at like 35-55 mph it shudders and sometimes cuts out for a...

    88 5.7 low on power

    I replaced the throttle body to intake gasket when I got the truck last April. as far as the fuel pressure goes, i do not remember exactly what it was but I remember that it was 1 psi over what is required. i think the main symptom that my truck has is that at below 2500 rpm it doesn’t have a...

    88 5.7 low on power

    Well here is a little update. While waiting for the parts to make the aldl cable, I got and installed a new coolant temp sensor. That did nothing. when I did get the parts in for the cord, I followed the video exactly and looked at a couple of other forums and videos about tunerpro rt but I...

    88 5.7 low on power

    it has had a tune up within the year. The tune up did not include a o2 sensor tho. I will look into the o2 sensor soon but that probably won’t happen till after I get the parts in to make that cable. everything mechanically is good. Brakes are never warm, fan clutch isn’t stuck, and both trucks...

    88 5.7 low on power

    Thanks for all the great info! I will check the cat out but i would be surprised if that is my issue considering that the previous owner put a whole new exhaust which I’m pretty sure included the cat on my truck.i don’t really remember the actual value of my fuel pressure, I just remember that...

    88 5.7 low on power

    When I test the fuel pressure in November, it was between 9 and 10 psi. there is no CEL. I doubt its transmission related as you can kinda hear that it’s not running right.

    88 5.7 low on power

    This is a long shot but here we go. I have an 88 k2500 with the 350tbi and 700r4. i have made a few posts asking for help with my pos obs and this post has the same theme. I have been battling low power off and on since august of 2023 and I thought that I finally fixed my power issues when i...
