Since new, I've noticed that my truck makes a ticking/pinging/tiny backfires when cold. I can't really hear it unless I open my window(s) as it comes out the back end and isn't anything in the front end (...its an exhaust issue). Is the truck just running rich when cold?
View 6 RepliesI have an 07 Sonata V6 Limited with 65K miles. Recently I've noticed at startup, the valves pinging and blue smoke coming from the tail pipes. Settles down after a few seconds and doesn't do it again if you shut it down and re-start. Last time I experienced this was on a Silverado with well over 100K miles. Back then it was valve seals. Could this be possible with 65K? I noticed in the maintenance log that they request having valve clearance inspected at 60K. Could this be causing my condition? I'm the second owner, so the 100K warranty is out of the question.
View 6 RepliesOver the last 2 days here in NJ were its been cold. When starting the Treg and get out of the car I smell a strong odor of gas from the Exhaust. This normal? Haven't had this smell before. Seems like it drives normal. Don't get to drive it everyday anymore. Only on weekends as my wife take the Treg to work now.
View 7 RepliesI have a 2016 is350. I just took off my is250 exhaust and installed it onto the 350. It is an invidia axle back paired with a tsudo midpipe. Since I have made the switch I have noticed several times after braking and coming to a complete stop within a couple seconds the exhaust "pops" usually 1 time and it is fairly loud. This did not happen on the 250. What is concerning to me is that it doesn't sound like normal exhaust popping/gurgling when slowing down or downshifting it is more of a sudden loud single pop after coming to a stop.
View 6 RepliesI was driving my bosses f550 with a 7.3, and while towing a loaded 40' flatbed of hay, it started bloing white smoke and lost all power and had almost no pedal feel. It wouldnt even go past 2500 RPM. Then, all of a sudden, it started billowing black, and BOOM backfired and shot flames out the exhaust. Then, I pulled over at a parts store and replaced the fuel filter, which worked for a while, but then it started blowing white smoke again. Once I limped it home and unhooked it, I took it out and let her rev a bit and it seemed to stop blowing smoke, but it still has less than the normal power it used to have. It has 226000 miles and is completely stock.
View 8 RepliesI have been having this odd issue where my car will back fire after a cold start. It only happens when getting out of first gear and going into second while driving (it happens as soon as I press the clutch pedal all the way in, and stops as soon as the clutch pedal is back out). It doesn't happen all the time, just every now and then. My only explanation of this would be that I live a mile above sea level (I looked at the FAQs and know that the car will act like its about to die on a cold start, yet it doesn't). So with my only "explanation" of this phenomenon being that I live a mile above sea level and the engine running rich for a few minutes after start up. My car is stock with the exception of the flapper mod.

I have a newly rebuilt engine on my 1965 Austin Healey 3000. When the engine is cold it makes a popping/backfire noise. After the engine has warmed up for 10-15 minutes, it doesn't make the noise anymore. See this video [URL] .....
View 7 RepliesMy F150 exhaust seems rather quiet when I first start it up, but after it gets warmed up good, the exhaust is much louder (which I like). I started wondering if I had a crack up front that widened out when it got hot, so looked under it when I got home today with it hot and still idling, but didn't see any cracks. Also I did not hear any noise like a leak. All sound was coming from the side exit pipe. So... what is the phenomenon that would cause this?
View 5 RepliesFor some time I have known the coils are going bad and cause occasional misfires but recently something new is added. Backfires and balking down to not moving. codes were po307 po300po430. the reader tells me the likely cause would be the vct solenoids. Also they offer a set of 8 coils at autozone with lifetime guarantee. Are these any good? I have read on here to beware of cheep coils. 2006 f150 5.4 miles is 119,000 have not changed spark plugs yet.
View 10 RepliesI have a 2006 ford f 150 with a 5.4 Triton 3v engine and every time I floor it and the engine reaches 3000 rpms the truck backfires and looses power. Sometimes it wont pass 3000 rpm it just stays there and backfire and have no power. Sometimes the check engine light flashes...... I took the coils off and looked at them and they all looked pretty clean. Also the truck idles rough and sometimes when it cruising at low rpms, and I give it a little gas the truck will randomly misfire and shake hard. also the engine sounds like a diesel engine........ What might be wrong.
View 6 RepliesI have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.
View 7 RepliesI just got my v8 3 days ago and when i floor it its almost as if the exhaust is back fire but like a rattling noise it does it in neutral and if I'm driving, Is this just because its new or should it be going in for service already??
View 4 RepliesAlright way to kick off the new year. I drove my car to and from work today... no issues. I get ready to leave to hang out with friends, turn the car on, and the message "Exhaust Workshop!" comes up. It then goes away, but the CEL stays on.
View 13 RepliesWell after 8 weeks on owning this touareg this is the second warning light we have to deal with and also had the dead battery scenerio which took 2 trips for them to fix.. Man this is crappy for sure. I am busy at work and do not have time to search around so any info would be great about another TSB that I have to take in to the dealership or anything.
View 3 RepliesTouareg C10 TDI ... I would like to do a full exhaust. Looking for input in options without losing any power.
View 2 RepliesI am a V8 owner and have about 6,000miles on the car...recently the car has been making really high pitch exhaust sounds (rasp/high pitch/weird) @ WOT...it did not do this before...
View 2 RepliesI just purchased an '06 V10 a couple weeks ago. Today, I was about 11miles into my 15mile commute when I noticed A LOT of white smoke coming out of the back. The only time I'd seen smoke like that before was just before my old Ford Explorer caught fire. I immediately pulled over and took a look. White smoke (maybe steam?) was billowing out of the exhaust.
I say steam, because it didn't have the strong diesel smell I would've expected. I decided I couldn't sit there parked by the highway, so I got back in the car, checked warning lights and pulled out. Within 1/2 mile, it was gone. Nothing. No more problems the rest of the way. What this might have been? I have 1100 miles on the vehicle and this is the first time it's happened.
2007 V10 TDI... I am experiencing periodic exhaust smoke. It lasts for a minute or so and goes away for a couple of weeks. It's not using oil. The dealer doesn't know but is checking with the factory rep. Any clues?
View 11 RepliesI drive a 2005 touareg with 111,000 miles. We are faithful with ALL maintenance. This morning I woke up to my car covered in ash (due to all the wildfires in the area I live...Idaho) and my exhaust warning light came on. It is steady yellow. Not flashing. My car drives exactly the same. I tried to contact the dealer but have not heard back.
View 2 RepliesMy exhaust system light came on today shortly after re-fueling. I called the dealer and the service advisor suggested that I open the gas cap and re-close it making sure that it clicks. If that is the problem he said the light should go off in a few key cycles. There is no warning in the MFI. In the manual it says that there is an MFI warning about the fuel cap that says "CHECK FUEL CAP" and that the message will go away in about 10 minutes after you click the gas cap and restart the vehicle. I do not have anything in the MFI and it seems to be running just fine. (V-8)
View 4 RepliesMy exhaust emission light has been coming on intermittently lately . I had it to the dealer last week but the light wasn't on at the time. The computer showed no error codes therefor they had no clue. When I took it in this week fortunately it was on at the time and must have triggered a computer error( cam fault ) What could this mean? I am supposed to take it back in a week. It seems to run ok but my gas mileage has dropped off about 2 mpg. there is only 22,700 on the clock...
