Interesting find this afternoon. Purchased a vac meter and there was no vac on the turbo side of the car. Replaced the vac line from the vac pump to the turbo side along with replacing a few line around the vac switches and got vac there now.

Does the temp sensor, single prong, possibly have na effect? My gauge is erratic, will peg at 120 for a few sec, drop to 85, etc. Generally holds at 85 while on the highway. When the gauge pegs at 120 I can hit the dash and it will drop to 85.

The car acclerates much better; however, the pesky smoke problem still exist.

It is strange ... the car idles fine with very little smoke for 14 to 15 sec and then drops a few rpm, no more than when the ac compressor would come on and a puff of dark black smoke comes out and continues for 14 to 15 sec and back to normal for 14 to 15 sec .... this pattern just continues.
