Well they are back in and it didn't fix it. The battery seems ok to me, starts fine every time. I have not done a test on it, though it doesn't take any time so I will.

John Speake has now rebuilt the MAF, tested the EZK and replaced the LH. In fact he told me he drove his own car around with the LH and EZK from me fitted just so he knew they were ok.

yesterday I set up a fuel pressure test rig so that I could drive the car and watch the fuel pressure as I drove around. Having done that I have 25 PSI at idle, 26 PSI at cruise, and 34 PSI at WOT. always pretty steady. that's 2-3 PSI below spec on all counts, but not enough to be causing the problem here I don't think. (and there is every chance my gauge is a bit off as it hasn't been calibrated in ages). So that satisfies me that the fuel pump, filter, and regulators/dampener are all ok.

I suppose the next step is to pull the injectors and have them tested and cleaned. I pulled all the plugs yesterday to see if there was any variation in color (and perhaps point us to a bad injector or two) and found them all even and pretty lean.

Going to call John Speake in a few min and bend his ear for ideas, I am about ready to throw a match into the tank and be done with it......
