i'm having a really bad bogging issue with my car ls in a 91 hatchback coverted to obd-1, there are no codes. the bogging issue happened at full throttle, when i go full throttle the car revs alil the bogs out, i can rev all the way out at partial throttle. any ideas of where to start looking would be great.

 

Sounds like fuel issue... have you changed the filter if you have then maybe the pump is worn out. That's what my car does and it was the pump being worn out after 16 years

 

i'll try and replace it. thanks for the info.
