2000 Jetta 5sp ALH, 285k.
My car has developed some odd behavior.
Here's my thread with it's (long-winded) story.

So my current concern has four parts. I don't know how related they are.
1. It's still hard to start. I must disconnect the CTS (I've installed a CTS kill switch which I have to use almost every time, unless warm and driven within an hour or so) and give it 8-10 seconds of glow. Then it cranks for several seconds before roughly starting and stabilizing itself. Just a little white smoke, longer crank + more white smoke. and I know my starter is not happy.
2. I call it the "first stop stall". When I leave the house, the first stop I come to, less than 1 mile, it'll try to stall. White smoke, unstable idle, sputtering. I first thought that i wasn't taking it out of gear soon enough, but it does it when rolling in N also. If I smash the "gas" pedal I can save it from dying (puffs of white).
The conditions are: engine cold, within one mile after a medium pull for under 1 minute. If it dies, I can start it again without much problem.
The white smoke has me thinking it's the timing. Most of the time it runs smooth and strong. It'll idle or rev in the driveway all day.
3. Another concern, When cruising in gear and I let off the pedal to allow the engine to slow me down, when I get back on the pedal, the engine sputters and I get puffs of white smoke until I get the pedal almost to the floor, then it straightens out. It does it with cruise engaged or disengaged. I can press the clutch and rev match with no problem.
4. There is a miss that happens at exactly 2050 RPMs. If i hold the pedal there it stutters just a bit, consistently. Enough to feel it. I'd had other "misses" that were solved by replacing the vacuum lines and sealing the vacuum pump. VNT actuator seems to be functioning correctly.
I replaced the fuel filter and thermostatic T and did diesel purge, may have help a little but not much.
Other info, I replaced the Crank Sensor (no change)
I use Power Service at every fill up (same station, I'll try a different one next time). The check valve in the fuel sender in the tank is removed. ~45mpg. I do blow out the soot regularly.
I do have the CEL with a code for CTS (this is because of my switch), surprisingly I have no other ODB2 codes.
There's a little vibration at idle most of the time (sometimes it's VERY smooth). It is due for a timing belt.
Normally, I have good power and no smoke (unless I floor it). I check my fluids very frequently and all seems to be at normal consistent levels.
New battery, new crank sensor, new fuel filter, oil change coming up, new glow plugs, tank sender check valve removed, new EGR, ASV is working, "new" IP. new CTS (green four wire). Cleaned ECU ground, cleaned IP harness connection, original clutch (catch point is near the floor but shifts easy). Intake is not terribly dirty.
I have no VCDS, I'm in Ashland KY near Huntington WV if anyone would be willing to meet for a scan n' chat.
Any thoughts? It's the timing, isn't it. Could it drive well and just have these issues with the time out? I plan on changing the belt soon and have reviewed the procedure, thoroughly.
