Car is a 90 model 13b non turbo starts up fine idels ok I know my Tps needs to be adjusted and its throwing codes for crank angle sensor and trailing ignition coil but even with those issues I should still have some momentum I'd assume but when I hit the throttle the rpm's drop or they go up and the car backfires please help I really want to drive this car again

 

im assuming that since you're having an issue with the trailing coil, some of the spark plugs aren't firing and some of the fuel is getting burned up in the cat... that would explain loss of power and backfiring.. if that's not it, it could be a dirty fuel filter, bad fuel pump, or a dirty gas tank for the issue of bogging..

 

Good place to start thanks now is there anyone on here selling a trailing ignition coil?

 

do a TPS voltage sweep to see where it is at and if it has any breaks in the voltage while applying throttle.

 

Ok

 

Does it bog out at around 3k? I know that when the OMP/MOP Goes out the car will start and idle fine, but when you drive it, it doesn't get any power at around 3k unless you really ease into it. But of course you will need to pull the codes again and see if it throws those codes. Hopefully its not the OMP/MOP because if it goes out, it might take the EGI/ECU with it.

 

No its not giving me any throttle at all it bogs as soonas I hit throttle weather I ease on it or slam it it dont seem to matter
