AudiSpaulding

i just changed my injectors the other day, and finished putting everything together today. went to start her, and she did not want to run at first. eventually she did, but with a slight miss it seemed. after letting it run for a good twenty minutes it seemed to smooth out, but still had a hesitation whenever i'd hit the gas.... any ideas?<ul><li><a href="http://www.motorgeek.com/phpBB2/viewtopic.php?t=24586">my project page for this</a></li></ul>

last time i had a hesitation, i chased the problem around the mulberry bush back to a clogged fuel filter and fouled plugs. check out your fuel filter, run the car for like, 100 miles or so, and check out the plugs. should be a golden brownish color. also, make sure shes got plenty of air to make up for the fuel. umm... you can try an injector cleaner too, sometimes little deposits from the factory can get lodged in the injectors and cause problems. start with basics, lemme know how it goes.

...fouled during re-start operation. Rockauto still has the oe w7dtc's available

basic settings on the fuel distributor and check the plunger for wear

You pulled injectors, lines, o-rings, seals, etc. It is entirely possible some crud got in injectors/fuel/lines, etc. Run some Techron through your fuel system. Maybe even two tanks full. Make sure your injector o-rings are sealed properly into the inserts. And, as said previously change that gas filter.

When I had a partially clogged injector, mine ran just like yours FWIW...

although I do still wanna check out the plunger, that's been on my list for a while now. Oh and I got a "new" O2 sensor as well, so thats going in too
