I've had some hesitation in the past when not quite warmed up, but never this bad. It stumbled at the next two stop lights before returning to normal. I had to wonder while struggling with this if the EGR is now trying to fail.
I re-read my previous post and wanted to clear it up, I was only laughing since you experienced the same exact things I experienced in the past with regard to the shocks. Laughing because it was similar, not because it was difficult to remove.. had to make sure I said that..
ok onto the hesitation, it could be the EGR, but it could also be what happened to me. The rubber diaphragm in the accelerator pump of the carburetor hardened up due to ethanol in the gas. That caused the car to surge/buck and die under the right circumstances. Eventually it got so bad I was feathering the gas just to get to the shop. I don't know if I mentioned it before, but it was something I was meaning to tell ya about. I was thinking about your engine the other day, since you brought back all those memories! That was another one of them.
Oh and the rear main oil seal leak, I had that too. I didn't replace it as it was starting to leak right when I sold it. No worries, the guy that bought mine only wanted it for the frame/shell. He was rebuilding everything! Dropping a 5.0 into it, etc.. I should've kept in touch to see how that went, but I was focusing on other things at the time.
but back to the surging, it's possible that gas with ethanol has eroded that rubber diaphragm, something to check out. It's not hard to get to, so it shouldn't be expensive. I remember back then 20-30min and the mechanic was done. No more surging after that.
You can test the EGR system, really simple.. Just remove the vacuum line to the EGR (plug it up) and apply vacuum to the EGR. Engine should cough and die from what I remember. If you have the Haynes repair manual they should be able to tell you how to test it, if I'm remembering it wrong.
