Got the car back from my daughter. mileage 248940, she drove the 190e almost 1000 miles in 3 weeks. All the GTP has been consumed, so I tested the compression and lo and behold, cylinder number one jumped up to 130 psi (after 3 revs - of the engine) it made it to 150 with 4 revs!
Looks like the GTP actually did something. I ran the test 4 times and very consistent. Actual readings:

#1 130
#2 150 (approx, wasn't as concerned with reading)
#3 150 (approx, wasn't as concerned with reading)
#4 150


Cylinder 4 also jumped up. Other items of interest on the way home from the fireworks display, I was told that the car started running hot. She said the needle approaced 120C, so they turned on the heater, and didn't boil over.


On a sad note, she hooked the bumper cover on a pickup's bumper and pulled it a little off,,, she was scared $#ITLESS, that I might be upset,,, I laughed,,, customized already,,,

So today I'm gonna recheck the Lambda and maybe go get another echeck. With the compression raised so much in cylinder number one, It's almost gotta pass,,,

When I pulled the plugs, one had this shiny black hard substance on it, on only one side of the tip. Here's a picture. All the others looked the same. This plug is from #3 cylinder. Can this be caused by a bad spray pattern? Or is this the result of carbon buildup released from the #1 cylinder that got sucked into #3 cylinder from the GTP. firing order is 1-3-4-2 right???
