ANother problem. a LRAGE Power loss

driving home today, i tried to get on it.. i have absolutely no power. It took me at least 10 seconds to reach 60. Also , then engine note has changed alot. i dont understand what this problem could be. I checked for the cat being clogged with a temp gauge. Off the manifold its 900F, before the cat its 750f and after the cat its 774f.

is there a check engine light on?

no, there is no check light.. ive done a tune up on it already. A new opti, plugs wires, fuel filter, o2. And i have a snap on scanner. Everything reads the way it should.... i dont know anymore:(

checked fuel pressure yet???

ur cat is clogges....it should b 100 degrees difference between the front and the back of the cat...

lol smartass

clogged** be**

ok mr grammar

hehe thank ya mr korndogg

hooked on phonics worked for me...

it worked for all of us!! yay

Make sure your plugs wires are going to the right cylinders since you changed your opti. Huge power loss like that usually means you have a plug wire messed up somewhere.

well. it was running ok after i changed the opti. and last night i was driving home. And the car almost stalled. it wont rev past 3000 and wont go past 10 mph.. even with it floored. I opened the hood and the exuast was so hot the entire engine compartment was lit up. i checked it with my temp light.. but it only goes up to 1300F. COuld it be a fuel pump? maybe all thoes problems ive been having are the fuel pump. Before this happened. I noticed that around 4500-6000 the power droped off alot. And that from 50% throttle and 100% there was really no power. Might even have more acceleration at 50%. Still no engine light

Oh and. I try and floor it. the engine sounds really different. it revs really slow. and is more quiet then before

i checked the fuel pressure... i dont know if im doing it right though. I hooked up the tester .. to the right spot i think.. it screws into the threads fine... but when its running or when i 1st turn it on the gauge dosent move.. even when i rev it. it dosent do anything.. almost like its not even hooked up...

correction... Fuel pressure is at 40psi

dude its your cat

thats what i said...but noooo... noone will listen to me....i only work at a damn muffler shop. and theres only a 24 degree difference on the cat...there has to b 100...

lmfao

i shouldnt say muffler shop....we do everything..cept engines..

y not engines

we do too much other shit.

pfft obviously not enough if yall dont do engines

thats what i said...but noooo... noone will listen to me....i only work at a damn muffler shop. and theres only a 24 degree difference on the cat...there has to b 100...

i told him that in his other thread. we just get no respect korndogg, no respect at all...

You gotta watch those gas pumps with the green handles. Are you running glow plugs?

check you plug wires. I had a similar situation. If you accidentally let the plug wires get near the hot engine or exhaust manifold, the wire will become hardened in a partiular spot. it's very noticable if you try to bend the wire, it won't bend so well. This will definitely affect rpms. I had one bad wire and I could not rev past 3000rpms with it to the floor. Also check for burn marks or black spots.

yeah it was the cats..

man - why's ur amp on the floor?

becasue i didnt put it in back yet

haha - did u run the power cables through the grommet in the firewall?

nope .. through the door..lol.. i just wanted to see if the amp and system would work.. so i didnt spend much time on it

haha - there's a grommet up behind the dashon the pass side

nope .. through the door..lol.. i just wanted to see if the amp and system would work.. so i didnt spend much time on it. what did you do with ur system.. ill buy it.. the mor eth ebetter

incase you ever want to run it differently

well i kind of want that amp u said u had.. along with the subs

haha - only got one sub - and i dunno if it still works. i assume it does....same story with amp....but i have no way of testing

Housy if you're willing to sell them i may be interested depending on the price

good job on the cat, when i did that i missed a little chunk on the side. it came loose while i was driving and screwed everything up. took off the cat the next day and it was just large enough to not travel down my exhaust to the muffler, where it would have really screwed stuff up...

HEY back off my deal RS thats MY AMP!!! :)

shut it, i only have 4 speakers lol

you shut it. I only have 2 speakers (subs) :D

i have 0 subs

lets settle this like men...... www.ebay.com :)

i was hoping for a duel to the death. thats the problem with kids today, no one takes the time to duel to the death anymore...
