FD broke down, fixed now backfires. Help please!
my FD broke down the other day. I was just driving it and the engine died and would crank but not start back up. I towed it back to my shop and later we diagnosed it as a bad crank sensor. one of them was reading no continuity. I swaped in a spare one from a spare motor and the car fired rite up. So yay figured the problem was fixed. Today i went to test drive the car and at about 3000-3500rpm the car will backfire. At idle if you give it gas the car will backfire also. car ran fine prior to the crank angle sensor problem and i dont have a check engine light. Does anyone have ideas on what it could be or what i can check out? need some help. Thanks

try resetting the ECU,,, sounds a little like limp mode (but no engine light????)
also make sure the 2 crank angle sensors are not plugged wrong way round (may sound really stupid but when i bought my car with problems 2 years ago,,, i had same problem and it turned out to be that.),,,(symptoms where rough idle back firing and would not accelerate, but did start up ok??)

weird tho, it idles normal, if you keep the rpms under 3-3.5k it feels normal, but go above that it backfires....
