car is acting funny. starts to overheat and all that other good stuff. header i believe is leaking and i think the injectors are clogged... so does this sound good to u guys.. gonna change the plugs, take out the stat until i get a mazda one sat???? also the gaskets that they sell in autozone or discount for the exhaust manifold are they crap???? someone told me that they just burn in like a couple of weeks???

did this just start happening all at once? i used muffler cement and steel wool for the gaskets on my headers.

yeah i was driving home from work and car starting jerking like if something was stuck in the injectors. and then all of a sudden bam starts to accerate. and i think the header gasket is gone cause i've lost alot of pick up. also how do you hollow out the stat?????

MazdaRx7Power

i'm waiting for responses see what i can do cause i wanna get this done tonight!!!

hyperdaddy7

what is a stat? i posted an answer for your acceleration problems on the other post...the header gasket leaking would have nothing to do with it..all that is going to do i make your car loud i drove around without a header hasket for a week, no problme just incredibly loud...

a thermastat... yeah so the nice thing is now i go to try and start my car and the dam thing doesnt want to start now... tried holding the fuel hose but still nothing, engine just keeps turning. so yeah i'm extremely pissed cause i probably need a rebuild now..

trust me on this one your flapper in the mass airflow sensor is stuck just take so wd-40 and free it up

it takes two seconds to check the mass airflow flapper, all you do is take the air box off the mounts and then take box off the mass air flo sensor it is connected by four bolts (that are like 10 mm i think), and then just push the flap inside, to see if it is stiff or stuck. if it is spray some wd-40 on it to get it moving again.

Now your engine is going to be flooded becasue your ecu has been thinking that your engine has been getting a **** load of air when you really haven't. That is why you were running so rich, and why it would only pull after 3k or 4k rpm's.

like i said my friend had the exact same problem with his t2, we couldn't figure out the problem and had to tow the car home. we couldn't figure it out the problem so we took it to two mechanics and they couldn't figure it out. then by chance we looked at the mass airflow and the flapper was stuck wide open. It sounds really stupid i know, but that was the problem
