What happen is there is no leak on the hoses, I change all my hoses and installed a new EGR valve and the problem still there.

I got my header today, I'm gonna pick up the gaskets friday and hopefully put it on saturday.
Sorry for bad pic.

what header is that

corolla header. He will need to get the pipe extended and have a second 02 flange welded on the b pipe too.

what is yours branded and what did the box yours came in say? mine was "Edge Racing Sport", and came with all the gaskets except the one to the cat.

My header is for the corolla, and I got it from NOPI and it's made by HP Racing.

The best way to find a vacuum leak it to spray all the hoses coming off the manifold with brake cleaner.




so how did it turn up?

Well you can definitely feel the difference in the header, from cracked manifold with a 12 yr. old cat. but I am still having problems with the car. I went to the auto parts store today and was going to buy the EGR valve but instead the sells man told me to clean the O2 sensors with gasoline and clean the EGR valve with brake parts cleaner, so I gonna see how that works.

LOL cleaning the O2 sensors with gas is just so he can sell you new ones LOL

gas can be used as a cleaner

not for an O2 sensor, maybe carb/choke spray, but i'd even be iffy on that. if the sensor is so old and worn that its no longer reading proper just replace it. you can get an OEM one online for relatively cheap, no soldering and splicing, just plugs in. i got one from http://sparkplugs.com/ for about $50. yours are a little more, but not TOO bad.

Denso OE identical O2 sensor 234-1053 234-1053 FRONT $77.48
Denso OE identical O2 sensor 234-2052 234-2052 REAR $40.58

hey dude did you fixedyour car fixed yett ...if not .... will for my car it pick up very slow i have a 5 speed same thing it barly move when you drive it and even if you floor it ... i found out that the disturbitor was sitting wrong you just might need to turn the disturtor to the the right spot ... buy you have to retared the distur. and reset it...

any update ?
I would like to know cause I have the same problem. I already change EGR valve like a month ago and nothing so I'll probably change my O2 sensors this weekend. if there is something I should know or could use, guys PLZ let me know

Do you mean the timing was off or the actual distributor was on wrong, I was planning on checking the distributor after I changed the EGR sytem.

I orderd the EGR valve + selenoid and the intake gaskets so I can clean the inside of the intake, I'll let y'all know what happens.

did you replace your O2 sensors ?

What is your MPG?

How hard was it to get the two discolored plugs out?

I guess they look like they have had exhaust gas blowing by them discoloring them.


Have you changed the fuel filter? It is a bit of a pain, but does make a difference, my wife filled our car up at a station known for dirty gas and we had problems till I changed the filter, ran some Barrymans and reset the ECU.

The timing shouldn't change on the fly, there are two bolts securing the distributor.

that coloration is NOT caused by exhaust gasses. its case by a small amount of current tracing over the porcelin and atracting oil particles to the paths where they get stuck. it'll clean right off with a little brake cleaner or carb/choke.

Not that I am doubting, but the discoloration above the threads and around the hex area of the spark plug on two cylinders in due to electrical current?


Even though two are perfectly clean above the threads?


A simple exhaust leak around the plug gasket would cause this, and the fact that he is losing power under throttle, when compression is higer so leak off would be higher. Perhaps it is just oil loss from the tube seals burning on to the hottest part.

yes, its current tracking. the other 2 may not have had any oil to track or it could be that 2 plugs had a larger gap/looser boot seal

its technical term is a corona stain
