detonation=burning smell?

[PearlBlue L]

thinking now it might be a clogged cat. i have bassani high flow cats and my tune all summer was pretty rich when i had my ported eaton and i didnt have the money to get a new tune.

heres the dyno vid of my a/f, very rich so im thinking it may of clogged it over the past 5 months.

What about the belt?

Yeah. Are you running an aftermarket idler setup to decrease belt slip?
I get the same symptoms,(smell and loss of power), that you described when my s/c belt slips on the upper pulley.

That would make sense right? Would the belt slip cause it the belt to get hot and smell like its burning? Again a dumb question for my own knowledge. If it is happening at 10+ lbs, I guess belt slip does make sense...

 

[PearlBlue L]

no its definetly not the belt. billetflow 100mm idlers. my tries will spin before the belt slips

i thought it was your cats until you posted the loss of power. maybe the heat buildup killed the power?

have u recently changed the tune? you know how you're supposed to have all electrical stuff shut off? my truck fell flat after installing a tune while my radar detector was on. i'd reinstall your tune just for the hell of it.preferably in a remote location. even if your problem is solved it cant hurt!

it just makes me wonder if any other electrics in the vicinity can screw with the tune? :shrug: good luck with it. hopefully the mogwai stays outta there!

the truck is now stranded in my apartment parking lot. it starts up for a second and shuts back off. i disconnected the battrery to reset the computer, reuploaded my down to the truck and tried to start it again and nothing but the start up then shut off. i tap the pedal for teh 1 second its running and nothing happens, no rpm rev, nothing at all. got a code and read it with the predator. something along the lines of #2 fuel circuit high... something along those lines. so after makeing a few phone calls and talking to a few people im thinking maybe my problems from the track and the other day on the highway and now today is all from a clogged fuel filter. now its so clogged that its not letting enough fuel get through to even start. i got the truck when it had about 17,000 miles on it and dont know if the first owner ever changed it or not. now the truck has about 51,000 miles on it and i have never changed it since 17,000.... so it hopefully makes sense and is the problem im having. problem is now i gotta get the truck from the apartment parking lot to my house which is about 30 minutes away so i can work on it in the garage.

does that sound like a reasonable answer?

anyone think it could of been the fuel filter being clogged giving me problems all week long???
