Repost: power loss issue

[nativetexan]

Ok. One question; what is CEL?

Also, I feel that I should say I did not put my air pump on, nor did I put the coal canister back on... Would either of those things have an affect on my issues?

@vile,
Can you refresh my memory of where the EST is on the 87 5.7 setup with the TBI? I don't think they found it. He told me mine doesn't have one. I was there when he was looking for it, so, I know he did try. Anyway, Also, do I just disconnect the battery to clear the codes? I talked to him earlier and told him it was the same... He said to bring it back and he could check compression and the push rod position..

[nativetexan]

ok, timed it at operating temp, and with the wire unplugged. I disconnect the battery and touched the red to ground. Is that good enough?

If so, then I am still having problems... what next?

You think it might be a fuel issue? The truck sat for about a year with the old gas in the tank...maybe a clogged filter?

[nativetexan]

Anyone? Is there anything else I should rule out before taking it in to the shop again?

[VileZambonie]

OK you cleared the codes but next time disconnect the negative battery cable and wait 30 seconds, don't play with the positive. Explain exactly what it's doing now and check for codes.

Ok, here is a detailed discreption of the symptoms..

In drive, if I slightly push on the gas, it will accelerate and shift gears just fine. But this is a impractical acceleration rate. If I try to push on the gas to get to a somewhat normal acceleration rate; the engine stops reving, and the truck stops accelerating... well, maybe not totaly, but less than when I am barely pushing on the pedal. This happens at pretty much any amount of me pushing on the pedal. thats about it. I was thinking of recording it on video and posting it. the same thing happens with the tranny in park. If i give it a little gas, its ok. If I push on it any more, it stops reving and bogs out. Kind of like a gargle... and it seems like if I kept doing it, it would stall.

Does the truck still have the factory catilytic converter on it? My brother in laws truck acted similar and the converter was almost completely pluged but could still drive with light throttle. My 98 camaro did the same thing it was cruising fine the felt like it died but kept running but would bog under any throtle once warm and the converter on it was cloged to the point engine temps rose and the converter got bright red! Wouldn't hurt to check it out if its still got one on it.

I'd change the fuel filter with each fill up for the next few fill ups.
Also dump the gas if it sat that long and fill with some fresh gas, and add a can of seafoam to the tank.

And if you haven't done it- Fresh plugs gapped correctly, wires cap and rotor.

[nativetexan]

Just got the cc changed when I got new exhaust. Cap, rotor and wires were changed within the year.

Did you check for codes?

check the TPS and check your fuel pressure too.

[nativetexan]

vile, I found a thread where you gave instruction on how to get the codes with a obd. But when i get the codes I translate them to numbers? I will check the TPS tomorrow, and try to get the codes. But I will need to know how to convert them.

[nativetexan]

ok. figured it out. no codes... is this because i reset them? you guys think it might my advance? do tbis have it?

[VileZambonie]

You should have gotten at least one code if you did it right.

You checked the TPS? You checked the fuel pressure?
