2004 Trailblazer 6cy. 2WD - has been experiencing a very rough idle, engine shudders - no matter how long it's been warmed up. Wants to stall off red lights and at very low speeds. Not throwing any lights yet - but the speedo is out ( a cam shift typical problem for this car) so I don't trust the console for lights. Worse when the heat or air is on. Rides fine with more gas/higher speeds. Definitely worse in colder temps but continues even after 40-50 mins of driving. I've heard a number of things, but can't afford to fix them all. I've heard plugs, dirty throttle camshaft, sensors, cam actuator solenoid, etc. All seem to have people who said it fixed and didn't fix the issue. Worried I'm going to stall pulling off a stop and rear end someone any day now. Where do I start!?

If AC is off, car stops screeching once running a moment. My mechanic said more torque on serpentine belt when AC on so he changed serpentine belt a few months ago and currently belt appears to be moving fine. He says compressor operates fine. Started about 6 months ago right after new transmission put in at dealership under Isuzu warranty. Mechanic stumped and waiting for something to break.
View 6 RepliesOur Pilot has started having an intermittent problem where it won't turn over, just a single click when you turn the key. The rest of the electrical things work. We recently had all of the sparkplug cables replaced 'cause of rats chewing. We had it towed to the dealer; they kept it overnight but it started for them.

View 4 RepliesGot a 1996 Volkswagen Cabrio with around 125k miles. Recently the check engine light came on. Had the code pulled (P0133 02 Sensor Circuit Slow Response) and reset but it came back on shortly thereafter. I've also noticed that the car idles strangely, generally after it has warmed up a little bit. Basically it will idle rough and sound as though it might choke out but if you give it a little gas it goes back to a normal, even idle.
Right now it's getting around 20+ MPG average which seems a little low but I only purchased it 3 months ago so I don't have much to compare it against. One other thing I've noticed is that the plastic molding around where the gas nozzle goes in is cracked which makes it difficult to fill it up since it doesn't make a good seal unless you position the gas nozzle just right.
Any thoughts on whether either of these problems might be related to the weird idle? How hard is it to change the front 02 sensor?
Will a 2011 Chevy Cruze 1.4L turbo engine wear out / break down / fail sooner than a 2011 Chevy Cruze 1.8L engine ( w/o the turbo ) ? Both being automatic transmissions. Driven by the same person. What is the gas mileage difference between the same two ?

View 8 RepliesI had a spark plug break on me and it caused a misfire. I took it in and the mechanic replaced all spark plugs and wires. After getting the car back, I experience an occasional engine hiccup here and there. Took it back to the mechanic and told me that he cleaned off the valves of carbon build up. This did not alleviate the current symptoms. It is more noticeable while I am idling. It feels like a jolt. It appears to be worse after a cold start. I do not have a check engine light or do I notice the RPM needle go wild. What is the mechanic missing? What could still be wrong with the engine? Vehicle is a 2001 Ford Windstar Sports SE, 6cyl, 3.8L ....
View 5 RepliesA friend of mine owns a 2002 Toyota Corolla with around 100k miles on it and it has some sporadic problems. Once in a blue moon the engine light comes on because of a misfire and seems to be around the same time it is humid and wet out (suggesting spark plug wires). However it recently sat overnight, after a slow rain, and would not even turn over the next day. The lights are not dimmed in the car but there is only a faint hum when the key is turned. What is wrong?
View 1 RepliesMy 2007 Pontiac Grand Prix loses power steering fluid within a couple of days of having the power steering fixed. I've gotten a new power steering unit, new hoses, had some kind of treatment put in to try to stop leaks, and nothing has worked. Every mechanic that's looked at it says there's no leak that they can see. What the heck is going on?
