fuel pressure question - KE-III
I did some work on our 1991 190E 2.3 that involved removing the electric variable pressure regulator on the side of the fuel distributor - easier access for removing the idle air rotary valve. The car had sat overnite before removing it, but I still expected some fuel to spurt out. No more than a drop came out. Is this normal? If there is pressure leakdown, would the injectors be the most likely culprit?
The car pretty much runs normally, but mileage is less than I think it should be, idle is sometimes a bit uneven or high, and the engine bangs around when started - but always catches quickly. Thanks for any input.
