If I'm going to fix an older car with a broken engine, what are the pros and cons of (a) trying to get replacement engine vs (b) having the engine remanufactured? [more inside]
We have a car that can't be started following a serious oil leak. The mechanic in the family has requested me to find someone who will steam-clean the engine on a mobile basis. I called a bunch of places, but none of them makes house calls, except for a guy who does pressure-washing, which our mechanic says won't work—the pressure will damage the electrical components of our elderly VW Vanagon. Do you know of anyone in the Portland OR area who does mobile steam-cleaning? Or another way to degrease the engine besides towing the car to the steam-cleaning place and back?
After a bunch of trips to mechanics, my car engine is hesitating/missing intermittently, and I would love a second opinion.
My 1998 Nissan Sentra GXE (1.6L) has been acting up for the past few weeks, in decreasing degrees of severity. After a varied set of problems and repairs, the engine now hesitates at random, more often when idling than when driving. It sounds like it's about to die completely and then returns to normal in a second. What the heck is going on? [more inside]
My car is doing something kind of alarming, intermittently. I'd love to get some guesses as to whether I need to see a transmission specialist or not before I take it somewhere. [more inside]
Are you an automotive engineer? Do you design engine control module firmware? Do you know or love someone who does? How is that firmware actually written? [more inside]
Why does my uncle's 1998 V6 Toyota 4-Runner misfire at highway speeds? Last month we drove from Los Angeles to Tucson and back, and at what seemed to be random points while we were driving the engine would buck repeatedly. Once it started, it would continue at all speeds, with the engine running particularly rough at low/idle RPM. We took it in to 3 different Toyota dealerships along the way, and to it's home dealership once we got back. They were all happy to service the vehicle, but none were able to fix it and two insisted they couldn't find any problems with the vehicle. [more inside]
Is there a precursor to Moore's Law for internal combustion engines? If so, can you provide details, please?
After having the A/C compressor replaced in our VW Golf, the engine idle speed drops way down to near-stalling whenever the clutch is released while driving. It pops right back up, but it's a bit unnerving. [more inside]
I'm having car troubles and curious if this is a problem familiar to anyone: [more inside]
I have a 1991 Honda Civic DX hatchback with ~125k miles on it. It runs like a champ, except when it doesn't start.... [more inside]
