mass air flow problems
Ok, I have a 97 sephia with 1.8 and manual. I bought it last summer and about 2 months after I bought it the exhaust rusted off and burnt the evap wires and screwed it all up. It killed the coil, ecu, and mass air flow sensor(supposidly). We fixed the wires, got a new ecu, and fixed the coil. Well with the maf sensor upluged it would run but had to crank it twice to start and gave me a big dead spot in the throttle and fowled spark plugs really fast. I finally got the money to get the maf sensor and it still didn't fix the problem. When you plug in the maf sensor in the air stream, it kills the car and you have to pump and feather the peddle to keep it running, this is with the old and the new(used off of a wrecked car) sensor. With it out of the air stream it runs great except the dead spot is still there. So what I did was tape the ends of one and leave it to the side plugged in so I get the air temp so it doesn't foul out the plugs, but no air on the sensor element to kill the car. The other thing is that on my scanner it doesn't advance the spark advance without air to the sensor. Oh it also drops my mpg from 34 to 21.
So what I am asking is does anyone know what it could be? Any help would be awesome.
