So, In plain language, are you saying to replace the injector wiring harness first, and then if that does not resolve the problem, to replace the malfunctioning injector, 2nd?

l still have not solved this problem, but I have a bit more experience with it. The car runs fine until it warms up. Even then it may run fine, but other times it starts to drop the #1 cylinder, and once it starts, it gets worse the longer it is driven. What I have found is that if I shut the...

So I drove the car yesterday. All the symptoms went away until the car was up to normal running temperature, then the hesistation and shuddering on hills started again. Oddly enough, after about 10 km of shuddering, the car drove normally again the last few kms. Its acting more like an...

Thanks for the input gentlemen! I forgot to mention a few things. 1. no smoke in the exhaust, so the cylinder is not getting fuel I guess. 2. I did try fuel cleaner and it made no difference to the hesitation on acceleration. Then this profound shudder on acceleration developed. 3. I did...

Today on a 90 mile highway trip our 05 Jetta Wagon started to shudder under load. Downshift to higher RPMs smooths it out. It was mild at first but by the end of the drive the car is almost undrivable. Idle seems a little rough also. Just did an oil change, replaced the air filter, and fuel...

I have had DTCs for intermittent on #2 & #4 glow plugs along with "signal too high or intermittent" on a couple of occasions in the last month. This produces a CEL of course. Anyone have experience with this and whether these are related? Also, seat heaters are out problem traced to a bad...

Both key fob unlock buttons stopped working at the same time a couple of weeks ago. Lock and rear gate buttons still work fine. I tried reprogramming per the owners manual and with Vagcom. No change. To the best of my recollection we havne't changed the batteries in the fobs. I would think low...

Shifting into 3rd gear is frequently (but not always) rough, with light grinding and/or resistance. No other shifts are affected. 139,000 miles. Anyone else ever experience this or have thoughts on the cause? Low transmission oil level? Adjustment of linkage? Worn linkage? Thanks in advance!

The last month or so I have been hearing a rattle or buzz for a second after starting. Sounds like a worn bearing rattle and my guess would be in the starter motor. Can anyone provide confirmation on this? Is my starter about to go out?

Just moving to the Yukon. Drove up the Alaska Highway a few days ago. This morning I started up in -30C (~-21F). In advance of the trip I did manage to install an oil pan heater (125W). This was plugged in overnight. It started but very reluctantly after quite a bit of cranking and firing of one...

I have had a fault code for over a year form my O2 sensor (rich) I replaced the sensor but the fault came back after a few hundred miles. Just had the recall done for ECM reflash and glow plugs (yesterday) dealer cleared the faults and didn't say anything about them otherwise. CEL back on...

The passenger side rear seat on my jetta wagon is stuck. Appears the latch won't disengage. Anyone else had this issue? It worked fine for a couple of years, then got difficult to release, which has now progressed to impossible. Anyone else have this problem? Find/suggest a solution? I have...

I have been running with a CEL for over a month with no performance issues evident, but want to get to the bottom of it. Autozone pulled the code for me. P2196 Definition: HO2s11 Sensor Signal Stuck Rich Explanation: Blocked exhaust Probable causes: 1-High fuel pressure, 2-Failed fuel...

I'm looking at an 86 Golf with 150K, 1 owner. What should I know and look for on this car? Key questions to ask? Thanks, george
