ok,
so, my 1994 corolla has its check engine light on. now i did get my o2 sensor replaced, i have no vacuum leaks, i have everything that i know of in running order. the only problem that i am still seeing, is my RPM's meeter stil shows that the engine starts at 2 Rpm's instead of its usual 1 rpm. my gas mileage is still a little down, (usually i get about 385 and now im getting about 330 plus or minus) what is wrong still?

oxygen sensors can decrease fuel mileage. I suggest you take it to the shop, and have them read the code

im not going to answer the question b/c i dont no. but i dont no if u realise this, or was just saving time, but the rpms of in engine is never 1 or 2. that means its at 1000 revolutions per minute. or 2000, up to what your engine can take...5500?? and that means that the engine is making a full cycle, crankshaft all the way around.

Might could be an injector is clogged. I'd suggest you have it checked at a reliable, competent, and honest shop (like the Toyota dealership). good luck!

well you sound like a guy with a lot of ar knowledge and obviously you cant figure this on eout. You should take it to some one with more knowledge of the situation then yourself. Take it to the dealership

It could be something as simple as getting a tuneup, It sounds like you need to replace your sparkplugs.

Have the EGR valve checked.
