Surgin and weirdness...........

Hey all,
Rolling on the mileage now. At 178k and still clicking along. I will admit...................I love this ******g car to death. Anyway, I recently notice a surging at the higher rpm range. Also, when I start it, let it sit and idle, after about 30 seconds, it drops to about 500 rpm and cuts out real bad, then slowly gets better and magically runs good. On the highway, if I run up the rpms slowly, I can feel it surging. I ordered new plug and wires. I put a new coil on recently, because the MSD coil is trash..............beyond trash. Anyway, I hope this cures the ailment. If anyone has a experienced this and knows differently, let me know. Hoping to see all of you at FF15'. I'll bring the hookers!!

How old is your front o2 sensor ? Front o2 should be added to any tune up list

Front 02 isn't old at all. I had a run on them when I went with a hfc and finally got motorcrap ones, they worked pretty good. Though, I did get a cel randomly yesterday. It was front 02 sensor lean. Cleared it and it hasn't came back.

Vac leak , have you checked the elbow from the metal tune to the intake from the PCV ?

Have you checked the hard plastic Vac tubing running on the intake , I have found a lot of them with rubbed holes in them and Vac leaks

I did replace the pcv valve,elbo and some of the tubing a while back. But you would think, if it were a vacuum leak, it would be more of a noticeable item. Like during idle all the time.

I replaced the pcv valve, grommet, hose from pcv all the way to the TB. I'll check them tomorrow, as well as the lines across the intake. You bringing doughnuts again this year?

Copper plugs? they have to be changed more often but i've had much better luck with them over any others, esp for high rpm use (AX)

I actually dropped in some other plugs, for the first time, a while back. I have copper cores, and new wires on the way. The vacuum lines are a pita for this car. No one carries them. the weird ones that is. They have two different sized ports and,not quite a 90, but like a 110 degree elbow. Stupid....................Anyway, I ordered in a new set from dorman a few months ago and put them on, after I destroyed a pcv valve. The grommet size is a random goat **** too.
