Loss of Power , Multiple Codes

[WNY964x4]

Ok , i was driving home from pa yesterday , had a u-haul 4x8 trailer with all my explorer parts in it behind the ranger , as i go to go up one of the hills , the truck bogs way down , wont go over 30 , 1500 rpm max , and the check engine light starts flashing , so i pull it off and let it sit , start it back up , and just crawl over the hill , coast down the other side , light is flashing again , so i pull off , finally the light stays on. So in my genius , i turn the truck off and pull the pcm fuse , put it back and then start it , truck runs fine. go to go up another hill , and it bogs again , light comes on , and i crawl to the truck stop , shut the truck off , let it sit , go to start it , no start. so mom comes to get me , i scan the check engine light , got the codes , remember the codes but not the numbers , her is the trucks info

2000 Ranger
3.0 - Engine #2
4R44E
160k miles on everything but engine
103k on engine

Codes:
HO2S11 No Switch - Reading Rich All Time
HO2S21 No Switch - Reading Rich All Time
EGR Flow Excessive
and for some reason
Keep Alive Power Low

Engine Bay felt like it was on Fire , More than the usual engine heat

well the truck got towed to monro muffler in erie , because the tow truck guy thinks it has a plugged cat converter , idk , but i need some ideas

so i assume the truck still isnt starting? pull the O2 sensors and try to start it. if it starts and runs with the O2's out, but not with them in, then it probably is a bad cat.

if it starts and runs with the o2's in, rev it up to about 3K in nuetral and hold it there. if it starts to bog down then stalls that would be indicative of a plugged converter as well.

it does sounds a lot like plugged converter symptoms...

mine did that too but it started w/ mileage that went down to 8mpg, check engine almost always stayed on, it started every so often then the mileage went down and the light stayed on eventually. couldnt figure it out. one day it sputtered and would barely pull itself, so i put it in neutral and held the throttle wide open said blow out or blow up, engine bogged a good bit to about 1800 rpm, followed by a loud bang like i blew something up/backfired. it revved all the way out and ran like it had no muffler, so i crawled under the trk while it was idling. sure enuff i blew the precat in half, took it to the shop had them cut it off, and i dropped it on the ground and a pound of soot hit the ground from the regular cat. thats when i put the magnaflow cat in, no problems til i started burning oil and the mileage went down again. i cut the cat out then so i wouldnt be changing cats once a month, now that the engine is dead ill be going back w/ a cat and shell be good once shes rebuilt.

wicked , i was able to get it started , only if i held the pedal to the metal , it would rev to about 2800 to 3000 then after about 15 seconds it would bog and then die , that was with the sensors in , unfortunantely the truck is about 125 miles away right now

Well i heard from monro today , well they talked to my mom first , and they said all three cats needed to be replaces , and that they got plugged because i had straight pipes on my truck , the repair would come to the tune of $3,000 , well , my mom , not knowing any better ok'd the repairs , she called me and told me , and i got into an argument with her saying i was not going to drop 3 g's on a 2000 Ranger with 160k miles for the exhaust repair (this was for all 3 cats , a muffler , which they assured her it needed , and the labor) she called them back and said that we didnt want the repairs. well they told her that they had ordered the parts and because they had phone authorization we could not back out , that we had to have the repairs done. well i know better than that , she told me , i got their number , and spent 5 minutes chewing the guy a new asshole , he tried to tell me that since my mom said ok that we could not back out , i told him that i am a mechanic , i worked at a repair shop , and i know that the customer can cancel the repairs even if you have the parts there ready to go , he tried to argue it out with me , and i told him that until there is a signature on the repair order they cannot do jack shit , he then said he had to call customer service to check this , about 10 mins later he called my mom to say that the had cancelled the parts , and that the total was 90 dollars for diagnostics ( me 1 ; monro 0 ) so anyway , the truck is now on its way back to ny on a flatbed , and our local exhaust shop said they can fix it for prolly under $1000 , i felt pretty good the rest of the day

strait pipes will not plug converters rather the flo will help clean them. if the o2 sensor sense lean it will level the system, not flood it and plug up the cats. what they told u was a load to begin w/.

 

[WNY964x4]

i new it was , my stepdad had straight on his f150 for 6 years and never had a problem , mine have been on for 4 months

 

[fleck]

Wow, I would go to my mechanic who has a 6 foot compressor and every tool imaginable in his garage, and get that sht fixed for like $200 LOL.

 

[Wicked_Sludge]

i agree with fleck. you can do better than $1,000.

order a few $80 cats from JC whitney and have a local shop zap them on for you (or clamp them yourself).

then figure out what caused the cats to fail. cat converters rarely fail on their own. something usually takes them out ( a rich condition, physical trauma). its extremely rare for all 3 cats to fail at the same time...so inspect everything that comes off the truck thoroughly.

 

[WNY964x4]

well wicked , i would replace them with a couple cheap $80 cats , but new york state inspection states that any modification to the factory emissions system is grounds for automatic failure , they actually out the vehicles on a lift and check everything , top to bottom , front to back

 

[rurouni20xx]

go back factory cat then, then check your o2 sensors injectors and plugs cuz you dont want to relive this.

 

[WNY964x4]

well i talked to the shop today , they pulled the truck apart , and after 8 years and 160k miles of abuse and driving over rough roads one of the front two cats decided to break up and clog the rearmost cat , so they are replacing the y-pipe with both cats , and the rearmost , they are replacing them with aftermarket ones that come in the complete factory style setup , so alot cheaper than the 2 grand it would cost from ford for the factory set up , since this truck has california emissions , well the truck will be done tommorow , and i will have my baby back
