Mazda MX3 Check engine light Problem
Hot or cold on normal acceleration it bogs really
bad and sputters and has small back fires.
If you get past this with heavier or lighter acceleration
it runs pretty good. Vehicle had a plugged convertor which was removed and the check engine light was on and the code was for a crank sensor which was also replaced. The check engine light is now off. Vehicle exhaust smells like it is running rich.

Check the fuel pressure if its within specs with a gauge-then check the TPS no. 5 closed and wide open throttle voltages and Airflow sensor no.18
