Yeap, it can be quite a few things... but like you / I said, when you have spare parts to do some testing, you (90%) find the problem quickly and effortlessly (if my English is good). Anyway, we are reading "symptom" of a problem on a mailling list. Everything you say or other says are assumption, like alsways. Dificult to diagnose without a smell, noise and feel. I personnaly have to look, feel, look, listen and smell an engine to began some testing. If i had this van in my shop... it would take me 30 minutes max to find the problem. Why, because i have over 10 Vanagons in parts available. Swaping is way more fast then reading and testing. I have to think more, i have seen that problem more then once. Anyway, i'm sick like hell (cold) so i should go to bed... i hate Canada weather, another 12in of snow tonight, 70mph wind.... beuaaaaaarrrkkk. I will move to the US sometime.... soon i hope. When Bush is out!!! ha ha ha ha... just a JOKE!!! Where is Mexico when i need it! :-) Regards, Ben Scott Daniel - Shazam wrote: > Timing advance curve certainly jumps to mind as matching the symptoms. > > However, on a 2.1 there is no mechanism of any kind in the distributor > affecting the timing curve. > > It is purely electronic from the ECU, > > And it's very easy to see that the timing does indeed advance when you > rev it, with a timing light.
