A1 problems (Topless bunny)

[txrocco at sbcglobal.net (Patrick Bureau)]

yep the metering plate has to be cleaned with carburator cleaner at least
every year to maintain a good functional movement .. as per dictating in
bentley in the fuel section :)

->Hey,
->(1.7L CIS-lambda, 2.0L 8v)
->(Metering plate sticky is at least one of the problems)
->Here is a log of the problems that the bunny has been having.
->- Cold start idle very low
->- Hot idle varies but most of the time is 1500
->- AC kickup works and is used in the am to keep it running.
->- bad hesitation esp going up hill
->- hesitation getting worse
->- noisy fuel pump
->
->stuff checked/replaced
->Fuel filter by fuel dizzy.
->Fuel pressure control (cold and hot) a bit low 40ish
->Fuel pressure maintain -- good no leakdown
->Fuel pressure system a bit low 58-62 ish (psi)
->
->pulled hose off gas tank.. (no xfer pump) dribbled gas.
->shot air up into tank thru hose.. got lots of gas.. dawned on me later
->that i had the cap on and pressurized the tank.. whoops.
->ran good for about 1/2 a day
->running like crap again
->check fuel pressures again.. same.
->began to notice that I had to feather the throttle like too much air not
->enough gas. did this only under load.
->
->Started hesitating today under no load condition
->removed sender unit, pulled filter out, cleaned it. some junk not bad.
->blew out drain pipe, sprayed fuel all over the place.. whoops. clean up
->aisle one.
->put back together still running like crap.
->everything says check fuel dizzy plunger.
->take off fuel dizzy, check plunger its fine.
->
->The point of the story.
->Now off to check the metering plate.
->Turns out that the plate is sticking.
->so if your car is hesitating bad, and the rev;s are slow to back down
->check the plate without the fuel dizzy. It might just be stuck.
