For several months my car has been stumbling when the torque converter clutch locks up. I changed the plugs and it stopped misfiring as badly as before, but there is still very little power. The car runs just fine until the TCC locks up at 40MPH. At that point, if I try to accelerate or go uphill the engine makes a slight pinging/rattling and basically refuses to put out more power until it downshifts or unlocks the TCC.
Gas filter is 1 year old, coils are within spec, and I cleaned the ICM contacts with no improvement in performance.
I didn't think to check my wires since they are new Taylor wires, less than 6 months old. Then I read another post about checking the resistance. Here are the results:
1 - .347K
2 - 1.14K
3 - OPEN
4 - 2.30K
5 - OPEN
I double-checked #3 and #5 half a dozen times, and couldn't get a reading from either of them. Then I removed wires #3 and #5 and the car misfired badly at idle. What the heck is going on here? Plugs #3 and #5 look fine so they must be getting at least some juice. But maybe not enough??
Now I'm pissed because the Taylors are past their 3-month warranty and I should have tried this test months ago
I like the blue color but I don't know whether I want to buy Taylors again or just get AC Delco OEM wires.
