Ive got a 76 924. my issue - it sputters.....all the time! at idle, reving. and at a constant speed. ive replaced the injectors and it runs like crap. i took off the fuel distributor and noticed a good amount of oil underneath and in the air filter. i think its coming from the hose connected into the air filter. would this be the cause of the sputtering?

I'm no expert, but if it's the crankcase breather hose I would say...Yes.

Also (I've learned from here) vac leaks..check for vac leaks..did you check for vac leaks?

One other thing to play with is the distributor timing. Start her up, loosen the distributor hold-down and twist away. If you've got trouble under all conditions it may be spark instead of fuel delivery.

Also, have you gone after all the usual suspects? Done a regular tune-up?

I quick way to check for vac leaks is to spray carb cleaner around and see if the motor run different, I might run better or worse but when it changes you know you found the spot.

Just don't spray all over like a mad man, be methodical about it.

Well its not the distributor. So spray the vac lines with carb cleaner??? Doesnt sound all too safe. But ill give it a whirl.

Also, I removed a pollution device that had a pulley, it had a tube that connected to this device that is circular and makes a LOT of noise!! it is located between the throttle body and the far injector. Can i cover it? or can i just remove it?
