I thought I had a bad injector on #3. With the motor is running, when I pull the lead to #1, #2, or #4, the engine stumbles as you would expect. If I remove the connector to cylinder 3, however, nothing happens. Even though I was getting a decent spray pattern when I pulled the injector out, I decided to replace the injector. Still nothing. There IS spark at the plug. And my noid light shows that there's electrical pulses at the connector lead. (IMG:style_emoticons/default/blink.gif) On the back of the block, under the air cleaner, I have three pairs of white wires that are solidly grounded.
Any ideas fellas? Thanks |

Valves on 3? Had you messed with the harness before this (rule out that the wires are all on the wrong sides) or was it running fine and then started to do this? Definitely check to see what color your spark plug is and if it is wet as suggested above.

Was running fine.
Started to get intermittant bucking, like the tps was going. Checked that out to be fine. Did the valves this spring, and thought they were dead on. I could recheck them. I'll pull the plug at lunch and check the color. Thanks QUOTE(Dr Evil @ Jul 20 2007, 09:06 AM)  Valves on 3?
