Daily driver engine problems.s
Ok boys & girls. I have (another) engine problem, and this one concerns my 33 mpg daily driver Volkswagen. So, here goes:
1. Engine coughs and wont idle. One time it died on me just as I was passing a car on the freeway. The symptom was almost as I ran out of gas. First I suspected ignition problems. It felt almost as it wouldnīt fire the sparks from time to time. I checked for spark. Spark was there,no problem, but I got new plugs and wires anyway. I bought a new distrubutor cap, rotor and breaker as well. Problem still there ![img]/wwwthreads_images/icons/frown.gif[/img]
2. Checked if it got gas. Yup, the pump worked alright, but I got a new fuelfilter and checked tank ventilation. Still it died on me! [img]/wwwthreads_images/icons/frown.gif[/img][img]/wwwthreads_images/icons/frown.gif[/img]
3. So now Iīm irretated and start do dig deep into it. It must be vacuum (eureka!!) or rather, loss of vacuum. So I replace all vacuum-hoses I can see. I clean up the carb and replace the gasket at the carb"foot". I replaced some electrical wiring going to the carb, which btw I have no clue why itīs there for, the choke is manual. Suddenly it will idle better than it ever did before[img]/wwwthreads_images/icons/crazy.gif[/img]. I celebrate this with a couple of beers and thinking to myself: Iīm d*mn skilled with engines[img]/wwwthreads_images/icons/wink.gif[/img]
4. Now, when I drove to work earlier today I noticed the following: Everything works fine until I reach 4:th gear. I can NOT throttle it very much until the vacuum is gone, and the engine starts coughing again. I installed a vacuum gauge to see what happened, it fell from good to dead when I throttled it in 4:th gear. I dunno why 4:th gear is the thief here....maybe because the engine have to strain itself the most?
Iīve run out of ideas now[img]/wwwthreads_images/icons/frown.gif[/img]. Is the carb leaking? Intake gasket? Itīs equipped with EGR, but I really donīt know what happens when an EGR goes bad ? Heeeeeeeelp !!
