Hey there my name is steven. I was apart of a racing club that all we did was drag race. I got a lot of experience working with 4 cyl cars im more use to small blocks and big block chevy's I have an 01 with a 2.2 and i need more fuel. I have custom cold air kit, custom cat back exhaust, fully ported manifold and head also polished and i have msd blaster coils. Platinum 4 plugs with hot wires. I am running extremely lean in fact so lean the inside of my manifold is a very gray color. I need more fuel i tried an aftermarket regulator but i couldn't get it to hook up right. I also need some suggestions. I am getting ready to buy a pacesetter and a new cam, somewhere around the 450 range. I am buying a rear oxy sensor delete what size of pipe should i run? I also want to raise the CR what would be a good company to use?

It's not because your injectors are too small, it's becuase you have a problem somewhere else. Get a wideband to check your A/F ratio then check your sensors.

As far as knowing you're lean, how do you know this for sure? You have a wideband? You found out at a Dyno?

The reason I ask is because with your modifications listed, you should not be lean whatsoever.

Also, how do you want to raise your compression? Boost or N/A?

I got some Z24 injectors you can buy

well every thing is showing lean. I have a white oxy sensor the manifold is gray and the a/f gauge shows extreme lean. I thought it may be the oxy sensor was bad. Well if it was bad wouldn't it throw a code and i have no codes. How ever i did by a nice code reader and it tells me that the oxy sensors are not operating correctly. Which is why i am getting the rear sensor delete from JEG's. Any other suggestions the car is really boggy at times and sometimes it dies all together. No codes are being thrown. Oh by the way my fuel pump is going out any suggestions. I think i just solved my problem. The fuel pump going out won't give me the right pressure. Not givving me the right amount of fuel.

wow, slow down. You have 2 02 sensor. The first one is for the A/F ratio and the second one for emmission. The first sensor can be bad and not throw a code. Unplug it and see if the car runs better. Or just change it. The 02 sensor that can have a simulator is the second one, not the first one. Jegs CAN'T delete it, they can only sell you a simulator.

Start with the small thing before jumping to conclusion.

ok i was a little excited the other day. I will try that. What about my fuel pump issue?

S10 4.3 Vortech fuel pump will work if you truly need the fuel. But with the mods you have a new stock pump should work just fine. Also, are you sure it's the pump? Have you checked the reg? If the diaphram inside is bad it may lean out the fuel.
