Hey everyone. I haven't been sharing some of the issues (minor) with the car lately, but this last one has me a little stumped and I haven't had much time to try and diagnose it much.
First the background:
The car started having low power issues starting at the end of January. I drove the car around a few times and figured out that one of my injectors was leaking. Fine, pulled it and re-sealed (new crush washer). It drove fine for about a week, and then low power again. Another injector leaking. I also noticed at this point that I had a lot of oil seeping out from the valve cover. I re-sealed the second leaky injector. While under the hood, I noticed some oil seepage from the valve cover above injector 1 (first from the left when looking at the engine). I pulled this injector (it was stuck in there good...I see why Nigel has that injector puller). The seating hole was interesting: full of sand and the crush washer was seized to the block. Well, after some careful work, I got the crush washer out and replaced it. Good news: no more leaking from the valve cover.
So, I decided to do some test drives to make sure everything was okay. Things seemed to be fine at the time, but I noticed my timing was off. (slightly retarded). So, I adjusted it and things seem great. Well, at least I thought it did. When I was test driving the car, I was looking for power to be back but used 2500+ rpm to test it.
Fast forward to lately:
I was driving with my wife and she was telling me that the car lacked power. I tested it again, and now the car drives kind of like a gasser. There isn't as big a kick of power down low, but as the RPMs climb, the power comes online and the car pulls great. I tested the MAF a few weeks ago and everything seemed okay on Vag-Com (I'm old-school). I did the actuator test, and the rod is moving.
Here is my setup: B203 injector bodies with PP520 nozzles, and a rocketchip 2/3 (set to 2) tune. I have a boost gauge and it seems a little funny, but nothing way out there. If I push the accelerator hard, I'll hit 15 or so psi right away, and then boost will build as RPMs/power builds.
Anyhow, I was wondering if anyone has run into issues like this and if they might have a solution for it. I haven't tested the MAF/timing in the past short while, but I see no reason why things would be off this much. I did also adjust IQ at the time to get rid of a slow down shudder, but it's still at 3.2. Any suggestions would be appreciated. I have a feeling I might have to pull all injectors again to see if I can find the culprit. I may also have to pull the glowplugs as I recently changed those. Just looking for other possible causes.
While this car has been reliable in terms of starting and driving to destinations, I've had so many little quirks with it lately. I'm not in a position to get rid of it, nor do I really contemplate the option, but I am getting a little frustrated with how finiky things have been on the car lately. My MK3 was much more rock solid than this. Anyhow...that's my three sentence rant.
Edit: sorry for the long post, and thanks for reading it all the way through.
