Chrysler - Ptcruiser :: 2005 - Carbon Buildup And Clogged
Our 2005 PT Cruiser has a 2.4 liter turbo. We had to replace the turbo at 78K miles due to “carbon buildup and clogged” so said the dealer. I can not get any local mechanic to tell me why this happened or if it is normal. My wife claims it is because I have been using the cheap, mid-grade gas. I tell her, no, it was because of the cheap oil I was using. I am now using synthetic oil. One mechanic said the turbo needs to be “blown out” occasionally, by either high speed driving or fast take offs. Bottom line: What would make the turbo carbon up so badly that it must be replaced? What can I do to have this not happen again around 156K? Must I always use premium gas?

My 1999 Accord with V6 and 240,000 miles pings on all gas except premium.I removed the upper intake manifold and found a very small pool of oil in the mainifold floor next to the opening that the throttle body bolts to.Also there is a small port in the upper manifold next to the throttle body opening that is about 80% clogged with a hard black deposit. This deposit is also in the corresponding port on the lower intake manifold.I had a new EGR valve and decarbonization done at about 175,000 miles.
The car runs great on premium gas but it is supposed to run on regular which is a lot cheaper.
Passat - Volkswagen :: Misfiring On Cylinder 3 - Carbon Build Up On Intake Manifold
I recently took my 2007 VW Passat 2.0T in b/c the check engine light was on. They initially replaced a leaking valve and a bad ignition coil, but the car was still misfiring on cylinder 3. They took off the intake manifold and found that there was significant carbon build up. The service writer said it was from "low-quality" gas. The car requires 91 octane. I've used 93 octane since 2007 but started using 89 octane around 6 months ago when the gas prices spiked again. Could 6 months of 89 octane cause significant carbon build up to the point it would trip the check engine light? Or could something else have caused it that I need to watch out for?

I have a 97 chevy silverado with a 305 v8. She wont start!! The truck sat for a year then i got it the other day. We replaced the sparkplugs and put new gas in the truck. The truck has spark, but it wont run. It pops and sputters when you put starting fluid in the intake but wont run. The old plugs some were wet and some weren't. All were black. I checked the fuel system, the pump runs as it should, and I checked the access valve and it has tons of fuel pressure. But wont run. There are no codes. Is it the distributor? Or is it the fuel pressure regulator?

I have a 1998 chevy silverado z/71 4x4. I had a water leak and had the intake manifold gaskets replaced. Ever since then, the check engine light comes on and it soots up the o2 sensors and the 4 plugs on the right bank. It may run good for a month or so and then it starts all over again.

Dealership put some dye in the oil last week and they're checking it today but they said it seems like it's getting flung around when it hits the axles. Waiting on a loaner because they want to hold it and let it run to see what happens. Whenever I look under it in my garage I see oil buildup on the oil pans passenger side and see a drop about the size of a dime.

My 2002 Explorer is having a problem. It started running rough suddenly and when I had it checked the # 6 coil pack on the spark plug was bad. We replaced it and it still ran rough. Found fluid on top of spark plug. At first thought it was oil due to the color but later figured out it was antifreeze. We do have a cracked thermostat housing that we tried to seal up a few months ago. Doesn't seem to be coming from there. This is my only reliable transportation.
View 4 RepliesMazda :: 1989 - Voltage Buildup On Outside Of Wire Between Distributor And Ignition Coil?
My 89 Mazda B2600i conked out on me suddenly about 10 days ago. My local mechanic replaced the distributor, cap, and rotor and the ignition coil and now it's running again. But starting it up at the mechanic's, I noticed a new faint sound like a clock ticking rapidly. From under the hood it sounds more like an exposed spark plug firing, but fainter.
After driving around to make sure I wasn't imagining it, I had the mechanic take a quick listen and look. He couldn't say for sure what it was, but said it was probably nothing to worry about.Taking a look under the hood at night, I saw lights running along the spark plug wires (continuous) and flashes of light where the spark plugs insert (frequent).
If one terminal of a volt meter is placed on the outside of the wire running from the ignition coil to the distributor and the other held in the air, the voltage rapidly builds up to 4 volts (a few seconds) and then immediately drops back to zero. This happens in roughly the same time frame as the flashes of light where the spark plugs insert, but I can't tell if it's the exact same frequency. What's going on?
Ford F-150 (2009-2014) :: 2013 FX4 - Ice Buildup In Front Wheel Wells
I just went to Steamboat this weekend which requires driving over two mountain passes in a snow storm...I only go if it is snowing. This was the first trip with my new 2013 FX4 and the front wheel wells filled up with so much ice that the wheels would rub after a bump in the road. The mountain roads do have lots of frost heaves so this would happen fairly often. The ice was all around the wheel well with a huge build up behind the wheel. It also covered the step rails. Would mud flaps do anything to preovent this build up? Or any other tricks?. Otherwise the truck did fine...

So I was driving down the highway on my way to work today and this thing fell off my car and I ran it over. It has a part number and it says that it is some kind of an air duct housing. I looked underneath the car and it was right inside of the driver's side wheel well.
My questions is, is this something I need to replace? The hose is still there, and the housing up top with the air filter is still fine. To me it just looks like this was something to keep the hose in place that draws air in.
The car is pretty beat up from an accident, but still only has 140,000 miles and runs well so I think it has a few years left, but I'm trying to keep costs down since it is just my "beater" car I drive to work.
Ford - Explorer :: 2001 - Backfiring Through Intake
I have a vehicle that came in on the hook its an 01 exploder4.0 sohc no start.. when cranking it will back fire through intake. no dtc's however its also showing all monitors not set?? dead battery erasing keep alive memory I don't know. Here's what i do know apparently it had gotten partial tune up all left side plugs and wires changed. All right side plugs and number 3 wire factory. I have plenty of fuel pressure. It appears that all cylinders have 150 psi for compression.
I changed all plugs and spark tester is showing there is spark at the plug, (yes at all) just cranks and cranks and then back fires. I also have removed front ho2s to rule out blocked cats, wires are not crossed. I have an rpm signal which should have been evident when I had spark and injector pulse. have not changed the wires nor the coil which is a 6 pack coil. (Boss refuses to get them for me since i have spark )even though I told him there was some arcing.

I have a 2001 Silverado 5.3L 4WD. About 40k miles ago the fuel pump decided it didn't want to work anymore, so it got replaced. Now, my fuel gauge is out of its mind. I have read that it could be a sending unit, or it could be an issue with the gauges. I checked the invoice, I got an Airtex fuel pump, which is apparently not as desirable sadly. Is there a way to check where the problem might be? Is there a way to somehow diagnose if it is the sending unit or the gauge cluster without spending a couple hundred bucks at a shop?

View 1 RepliesSilverado :: 2001 - AC System Making Lot Of Noise
I have a 2001 Silverado 5.3 liter extended cab. Recently have been having issues with the A/C system making lots of noise. I have identified the noise to two spots and I believe 2 actuators..
1) behind the glove box to the fresh air / recirc door there is a constant clicking / grinding noise. Toggling the recirc button causes the noise to oscillate and the recirc door can be moved by hand, so seems the actuator is basically gone...
2) When the mode is to face only there is a gurgling / clicking noise. When I move the mode selector a little bit off of face only, the noise seems to stop.
I have been looking and looking for a solid write up for the recirc door, can't even seem to find anything that is solid on the part number for that. Seems like I could probably get my hand up behind the glove box to take off that actuator and get the part number, read a couple of write ups that seem to suggest that it is incredibly tight and hard to get to, but it can be done.
Wondering if I just remove the top of the dash while going after the mode door actuator to make life easier? And do I need to get in there with the blend door actuator while I am doing the other two? No dual climate control, so does that leave me with only three actuators? I have the "automatic" a/c controls which are knobs on the dash, I believe these are automatic, not the slides that I believe are referred to as manual?
Silverado :: 2001 - Service Engine Light Has Been On
I purchased the vapor canister vent valve and purge valve as the service engine light has been on and this are the contributors. I want to know the location of these and how to access. It appears that they may be by the fuel tank and I don't know if I need to lift the box or something to access them. It is the 5.3L V8.
View 5 RepliesChevrolet - Silverado :: 2001 - Stalls While Driving
My 2001 Chev Silverado 1500, 5.3L, 260,000 K miles may finally be near the end - It has been running great until this week. I live in Portland - weather was down to about 10 deg F a few nights and when it warmed up again the trouble started. After starting cold and driving for about 15 minutes it starts stalling out.
Sometimes it will fire right up again and I'll hardly notice except for a momentary drop to 0 on the tach. Other times I'll have to pull off to the side to the road and restart it. However, 2 times now it would not restart and stay running. It would either fire up but then die within 10 seconds, or it would just crank. Both those times it did restart successfully after 40 minutes had passed total and it drove fine afterwards until I got where I finished my commute (about another 5-10 minutes of driving).
I took it to a mechanic who could see it stall but was not able to duplicate the 40 minutes out of commission thing. His fuel pressure gauge indicated that the pressure was fine during the stall outs. The mechanic ran the computer diagnostics but didn't see anything unusual. He wasn't really sure what the problem was. He recommended replacing the fuel pump and fuel filter anyways - but couldn't say if that would make any difference.
Should I start throwing money into new parts or move on and start looking for a new vehicle?
Silverado :: 2001 - Front Suspension Bumps
I just recently did some work on the front end of my 2001 Silverado 2500HD (Replaced hub bearing assy, rotor and pads), and while working on the front end happen to notice something I need some guidance on. I happen to notice the bump stops are basically crushed as if the vehicle just sits on them all the time. Would it be worth it to replace these and would they just get crushed again, and further, should I adjust the torsion bars a bit to lift the front end up off of these?
I don't want obtain any huge lifts, just want to get off the bumps and maybe improve the ride a little bit in the process. I also did have a bad hub bearing on the drivers side and after seeing this bump stop wondering if that might be why.
Silverado :: 2001 - Starts And Instantly Dies
I have a 2001 Silverado 5.3 with 145,000 miles. It runs great, lots of power and starts immediately, except for the other day. I drove to work and it was up to full operating temp, shut it off and came out 2 hours later and it cranked just fine and fired but died immediately. Repeated attemps got the same results. It would run for about 1 second and die. I tried starting it about 10 times in a row. I tried it again an hour later and its run perfect for the last 2 days, no hesitations.
The outside temp was about 65.
No check engine lite or any other lights came on.
No weird sounds.
New battery.
The fuel pump was changed out at a reputable Chevy dealership 3 years ago and about 40K. I haven't checked for any codes, or fuel pressure. It acts like a fuel pump failing, hiccups once in awhile and then leaves you stranded when you least expect it. But.....It started up instantly after sitting for an hour, meaning it had fuel waiting in the wings. I am thinking its likely electrical, a sensor? But shouldn't I be getting a light?
