Okay well I was driving my car a lot yesterday... It was running fine, I shut it off, and when I restarted it, it was missing. I figured it would go away in a few minutes after it warmed up some, but it didn't. It's been missing steadly since.

Today I checked the plug wires, all of them are fine, wern't touching anything hot, and were clipped on the spark plugs and cap. I checked all the spark plugs, they all looked pretty much okay, except for 6 and 8, which looked a little light, as if they are running slightly lean.

I then proceeded to let the car idle, as I pulled the injector connectors one by one, noting how the idle changed when I pulled each of them. Then putting them back. The idle dropped and got rougher for each injector, then when I got to Cylinder 6's injector, the engine didn't really change very much. So I am thinking something's up with Cylinder 6... but what should I do next?

The injectors are rebuilt injectors out of an 89 Camaro. They were pretty much freshly rebuilt when I put them in, all of them tested between 16.8 and 17.8 ohms. Could one of them be bad now?

I checked vacuum, it's staying steady at 21" at idle, very very little fluctuation, so I am pretty sure I don't have any vacuum leaks. I pulled the connector to the MAF and let it idle, still had the miss, so I don't think it's the MAF. The oxygen sensor is about 3 months old, AC Delco, so I really don't think it's that either, and it misses in both open and closed loop.

Any ideas? Should I replace my spark plugs to eliminate the possiblility of one of them being fouled?

I'm going to check the ohms on all my injectors next, I will post the results when I am done. In the mean time, anyone have any suggestions?

 

Checked the Ohms of my injectors...

1 - 17.5
2 - 16.7
3 - 17.4
4 - 17.3
5 - 17.4
6 - 5.7 (gotta be bad right?)
7 - 17.3
8 - 16.9

Now it makes sense, no wonder I had no real response when I pulled the connector off #6 at idle. Now I need a set of injectors I guess. There's nothing you can do to fix them is there?
