NorthWet Posted September 18, 2005 Share Posted September 18, 2005 It would be useful to know exactly how you ruled out spark problems. Just swapping out the plugs isn't conclusive. I would be very suspicious of the sparkplug wires, and carefully check the distributor cap (including where the plug-wire connects; for corrosion) and rotor. Ignition is the most likely problem. What makes you think that you are down one cylinder? Did you disconnect (and ground!) one plug wire at a time until the car ran the same?

Vanislru Posted September 18, 2005 Share Posted September 18, 2005 With the car running does the motor sound different when you pull a plug wire? Try all cylinders just to be sure. From what you've described it sounds like an injector. Take an ohmmeter to the 2 injectors on the passenger side they should be around 2.4 ohms if my memroy is correct. In any event they should both be within a few tenths of an ohm of each other if ones lower replace it. Very easy to do, remove the 2 bolts on the fuel rail that'l free up the one side, then remove the hose clamp on the injector and the 2 bolts that hold it down. easy as 123...

Scott in Bellingham Posted September 21, 2005 Author Share Posted September 21, 2005 I checked out the Ohms on the dead cylinder injector, it was a open curcuit, replaced the injector with a used one , and now it runs on all 4 , took it out for a drive, that thing is a rocket compard to my spfi ea82 thanks for the advice, this car will soon be lifted, other car will go up for sale Scott Quote Link to comment Share on other sites More sharing options...
