This is getting ridiculous

[The Devils Own Chariot]

I just got done putting new brake pads on the sy. I then took it out for a test drive. I hit the gas going up this hill and when I reached the top I stopped to turn around. That is when I noticed a burning smell. Now the sy has no power at all. It runs super rough under load and is about as fast as my 4cyl camry. The only way I can describe it is like only 3 out of 6 pistons are firing under WOT. There is no engine noise it starts fine and idols fairly well. I hooked up the old datamaster to see if that could tell me anything. From what I could tell every thing looked ok. It’s a stock truck running 15psi. I have really been through the ringer with this truck not working right. Im just really fed up :shoot: and disappointed. Anyone ever hear or had anything like this before.

Something doesn't add up here, if you have that much of a power loss *something* has to be seriously wrong. We are going to need more details to be of any help.

Did you check all the plug wires?? maybe one touched the dp ?

What did you use to jack it up with? Just a thought that maybe you accidentally crushed something....

Not to play Cpt. Obvious, but did you check to make sure that the pads aren't sticking? Always checked the thing you messed with last before the problem started. If the pads were sticking, it would create a burnt pad smell and result in reduced acceleration. However, it would still crank/idle fine.

The problem seemed to occur when you hit the brakes at the top of the hill. Something to check.

If does turn out to be a stuck caliper, try cracking the bleeder screw open and see if that relieves the pressure. If it does, you probably have a bad brake hose (all too common on GM front hoses). If not, the caliper itself may be bad. Either way, let us know what you find out.

Re: This is getting ridiculous

Thanks for all your replies. From what I can confirm its not the breaks sticking. Its something engine related. I know its tough to diagnose anything with the small about of information I have given. I am going to look more into it today. I was just to frustrated to work with it any more over the weekend.

I used the stock jack in the area designated on the frame to lift the truck.


I was just wondering mostly if anyone had something like this happen before. I will let everyone know what I find today.

Are you sure you didn't pinch a fuel line?

Re: This is getting ridiculous

BTW, going WOT when the truck isn't running right is a big no-no

And the winner is....
plug wire melted against the downpipe!

I checked that before but I could not see the full extent until I removed the upper IC. The person that put them in before did not have them routed very well. Got new wires in and I used some wire ties to secure them down better. The sy is happy once again.

I know someone who's running a special on wires this month - :lol:
