how do you know when ones EGR is bad?

95BlackStang · February 25th, 2009, 08:29 PM

i think thats the problem ive been having for a while, some days it feels great and then it out of nowhere it gets all boogy and takes for ever for the RPM's to rise and i feels a mojor power loss. so what you guys think

Trick Tuners · February 25th, 2009, 08:58 PM

Not sure. The egr is off at idle and wot. Can you describe the symptoms better? Typically with too much egr you will feel it at part throttle as kind of a shuffle.

95BlackStang · February 25th, 2009, 10:36 PM

symptoms are:

slow acceleration
popping sounds from exhaust(connected to slow accel)
engine feels like has a lot of resistance or load when giving it gas

Trick Tuners · February 26th, 2009, 11:17 AM

Maybe the cats are clogged? Is it slow acceleration at WOT?

TKOTLARZ · February 26th, 2009, 08:55 PM

95BlackStang · February 26th, 2009, 11:06 PM

dam, so what do i do about this other than replacing the mid pipe?

Traidmarx · February 26th, 2009, 11:34 PM

well man seems like we're in the same boat....i'm having all the same problems you are it seems.

95BlackStang · February 26th, 2009, 11:54 PM

its a sad day indeed

. so what causes this to happen?

Traidmarx · February 27th, 2009, 12:04 AM

i wish i knew i'm leaning towards the egr in mine as well, i posted another post in the 5.0 section a few mins ago, about my problems, i've replaced pretty the whole fuel system and ignition system. and still the same symptoms but at wide open throttle it runs fine most of the time. but at crusing speeds it will sputter at random. no particular rpm seems to set it off. Just at random, yet it can be sputtering the whole time and i can push the clutch in and it'll rev up fine. Sometimes i have a problem with it starting i'll have to sometimes hold the throttle just a lil bit for about 15 seconds when i 1st start in in the morning or the car will die sometimes, The motor shakes at idle. sometimes so bad that the car is shaking. as far as that popping noise it doesn't happen very often at all but occasionally when its sputtering if you give it full throttle to even it out sometimes you can hear it pop...does that sound simlilar to your issue??

95StangMX · February 27th, 2009, 12:28 PM

take the cats off and see if the problem goes away. Check the laws in your state if the inspection for emissions is visual then take them off and hollow them and put them back on. I used to have a long extension for a air ratchet that I welded some blades (kinda like arrowheads) and I could hollow them out in just a few seconds.

what about an o/r pipe, is it a straight foward swap

95StangMX · March 1st, 2009, 12:59 PM

yeah as long as you dont have emissions testing, and if you do just swap it back and forth, keep the old one with cats for when you have to get checked

95BlackStang · March 1st, 2009, 11:36 PM

ive been looking into them and i see i have three choices, o/r H,X and a prochamber. whats the diff between these?
