AAZ slight surge at idle
« on: June 17, 2010, 12:01:52 am »
Recently my engine has starting at idle (about 1000rmp) and mignt surge 150rmp for a second or so.  It does this a couple of times in a row then seems to idle smoothly, maybe a few rimp higher than normal.  I can even hear my turbo pick up speed when this happens. 

I am thinking it is a leaky or sticky injector?  The engine has close too 400k km, all original save timing belt.  I plan on pulling it after I get my 91 passat wagon w/AAZ on the road later this month, and keep it as a backup engine, just in case...



Under way - 1991 Passat Syncro Wagon w/m-tdi

1991 Passat GL Wagon w/AAZ conversion (now using engine/tranny from 1993 Passat

1993 Passat GL 1.9 Diesel (RIP 385k km, engine, tranny, clutch all original)
