I'm driving down the highway when suddenly the Z starts to "sputter" infrequently. It gets worse and worse and more frequent. It felt like the fuel was getting cut off somehow (so it seemed). For a second every so often there was a significant loss of power.

It got to a point where the car was no longer driveable so she was towed home. The car would turn over with a little bit more effort involved, but wouldn'r crawl no more than a couple feet before dying.

I changed the fuel filter but that did not remedy the problem. A little side note here; I noticed that the radiator had to be replenished with fluid too. I had the head gasket replaced about 50K ago. Any ideas? I hope I provided enough details. Thanks!

on the head gasket note. check the oil, see if there is any milkey white stuff or water in it.

as for the fuel. check the fuel pressure regulater on the fuel rail, check for any leaks or cracked hoses.

if you have checked all of this and it still acts as if there is no fuel, check the fuel pressure, should be at like 32 or around there. then check the tank to be glogged or anything..

let us know what happens.

Check if your injectors are clogged.. I jus finished installing my injectors and wow! 2 1/2 years of figuring it out has finally paid off!

injectors are a huge thing. one of mine were leaking all the time, then it changed to being clogged shut and that cylinder wouldnt fire.
