egr ?'s

[playmategirl]

i have an engine code it says egr flow insufficient...... im guessing in short i need a new egr. my ? is can i get egr block off plates for my 1mz ? if so will i gain anything from this at all? or will i suffer? the only place to get one is toyota. or can i just clean mine and see if that helps?

Have you tried cleaning the EGR valve? Sometimes I heard it just gets clogged up with carbon build up that it may throw a code.

[playmategirl]

ill try it and see.

what are the emissions standards there in NC? i could just remove the whole thing and get a little power from it.

[Eye8Pussies]

yup, you can always cap it off....and then use a resistor to trick the ecu about the egr temp


but also know that you won't be able to pass your emissions without it

i got that same code, havent cleaned my egr since i cant get it off, im learning to live with the code until i have enough money to purchase a new valve.

You won't gain anything but you will emit more pollution for the rest of us. Just clean it. You will need to use some PB Blaster or like on nut overnight and maybe a crows foot wrench to turn it off if there is an access problem.

You might gain a little power, such as Eye8 said. All the EGR basically does is recycle the exhaust gas, so if you remove it, then you are letting more fresh air into the combustion chambers rather then used exhaust gases.

ok thx ill see what i can do with it.

Excuse me? EGR gases lower combustion temps and lower the production of N0x, a serious contributor to pollution. The EGR is shut off at idle and at WOT so you don't loose power. It is active at cruising speeds. Got dyno tests that show any significant power gains without EGR?

[geoff5093]

I dont have dyno tests, but i've heard from people that have gotten rid of it that they feel more low-end power, but I guess without proof then you wont believe it

well u shouldnt do it to gain power, there isnt really enough to free up. the car will pollute more and i may ware out the cat slightly faster as well. but if u want to save money by removing somthing instead of spending money to replace it and you state will "allow" it then its an option. quite a few people here have done it and reported small power gains and no ill effects with performance anywhere in the rpm range. the choice is yours.

The Butt Dyno is quite subjective and wants to feel more power. It is unreliable especially when little to no gain is the reality. But I guess science has no place when perception is the goal.

if i do it it wouldnt be for power gains. it would be just to fix the bogging down prob and that stupid engine light.
