I replaced the wires and plugs.

My leading plugs have the normal light carbon coating, but after inspection the next day I notice light brown spots on them.

My trailing plugs...well...one looks ok. Coated a little more than the leading,...

... but the T2 (rear?) is caked with it. The grooves are filled and much dirtier than the others.

I might be down on power, but I'm not sure.The car was running like crap one day and settled down, but I might just be injecting my own negativity in there because of that.

I did not see any obvious damage while I was in there, but then again i was not rally looking that deep. Just in the area where the wire attaches.

I checked my records and I had the number 2 (thats the rear rotor, right?) trailing coil replaced 11,000 miles ago at 89,000 miles. That is the plug that is caked up very badly and the one I suspect is not working.

Digging more ...it seems I've replaced a leading coil as well...record doesn't indicate which.

I checked for error codes ...my first time. I was watching for the check engine light to blink...nothing.

Thats the right one, right?

Anyway, no lights that I saw flashed.

I think I replaced the battery after having the the T2 coil replaced so they may have been cleared...but that was over a year ago.

I ran the 40-70 in 3rd gear test I described on the robinette site and it seems that I am indeed missing HP.

As a benchmark, many owners were asked to time their cars from 40 to 70 MPH in 3rd gear.

How to Measure Your 40 to 70 Acceleration Time :

Start in third gear at about 35 mph, floor it, start the stopwatch at 40 and stop it at 70. Do it on level ground and time going both ways if possible and average the runs.

On average, a stock car should do it in about 4.9 seconds and a slightly modified car can bring it down to the 4.2 second range.



Using a stop watch I did three runs with my stock 93 Touring with 100,000 miles, 3/4 full fuel, and the temp here was 88 degrees.

1. 6.1 sec ...with my wife in he car too.

Dropped her off and went solo...

2. 5.5 sec ...felt as if I hit the trigger to early?

3. 5.7 sec ...that one felt like I slipped on the trigger

4. 5.6 sec ...felt about right, but I hit a very slight uphill grade at the end

Well unless I see some similar times, it looks as if I am down in power as I suspected. By the 4.9 benchmark I'm down around 15% and I the fouled T2 plug makes me think spark.

I'm lost and need help.

I need to find out what is causing it either from you or a source you know of.

I should have stated that I changed the plugs and wires to reclaim the missing power. So it was gone before the plug and wire job.

The car seemed fine. One day we started it up and it idled like crap. It settled out...but without as much power as before.

Then came the spider...err...I mean the plug and wire job.
