I pulled the motor out of my 1991 integra rs to change the transmission because it was slipping. Anyways, when i put the motor and trans back in, the car is getting hard starts and rough idling. There's no power .... I checked over everything ... seems to be hooked up right ..
Any ideas where I should start ?
I checked the wires, distributor cap, plugs, fuel filter . I'm not too sure if i mixed up one of my Vacuum lines ...
- The motor ran fine before I pulled it out.

Any help would be appreciated .

Thanks,
