1992 4.9 injector replacement
Ok folks I changed my injectors from MULTEC to 5.0 mustang injectors BOSCH and my rough idle is gone,no more hesitation on acceleration (bog)I tested all injectors with an ohm meter and they all checked out OK at 16-17 ohms except for one which was 7.8ohms.(this injector was causing all the symptoms)I just wanted to say thanks to all who posted about this problem and how to fix it.CadillacOwners.com ROCK'S.

Re: 1992 4.9 injector replacement
Besides being unreliable, the stock injectors plug much more easilly. I got Accel (Bosch) at Jegs for a 5 ltr (305) chevy, same as 5.0 Ford. Cheaper than the factory replacements and better all around. Actually easier to change on the 4.9 than the 2.8 that came in the Fiero.
