what about when the car goes into closed loop and the o2 sensors are warmed up the fuel trim changes according....sure driving at minimal load will make the car heat up faster but i dont think idling the car at startup will damage anything as the pgfi will create the best fuel trim to prevent damage. the 02 sensors generally heat up on 60-90 seconds and then trim goes to closed loop.

I can understand the thought that letting it idle to warm it up is the right thing to do. Across the road from a business I had was workshop that rebuilt a customers engine and they were very good at what they did. The customer left the car there for over a year in storage while he went overseas. Every morning they started it up and drove it across the road, leaving it idling while they sorted the other cars out, brought it back across and turned it off. Same at the close. When the owner came back to pick up his car he brought it back and complained the engine was knackered and they had done a crap job. They argued it was knackered from all the cold start idling and he shouldn't have left it there. I have no idea how that one got resolved. Apparently it can also plug the cat because it's cold and stays cold at idle, so it can't burn off the carbon as it normally would. Last edited by sierra; 06-20-2013 at 10:51 PM.

1) you're claiming that modern engines run so excessively rich @ idle that fuel washes past the cylinder rings (which causes tons of ring & wall wear and engine bearing wear as fuel is a horrible lubricant). What's your A:F at start-up? 2) the alleged excessively rich start-up condition goes away when you go into gear at low rpm? Are you saying the ECU realizes you're in gear and adjusts the A:F? Otherwise you're just getting more revolutions (even if it's less time) with an excessively rich A:F. Not to mention the oil pressure... 3) have you ever seen an accurate oil pressure gauge on an ice cold engine? You can drive the car as gently as physically possible and still see 100+ psi @ 2000 to 2500 rpm's. What's the oil pressure relief valve on these cars set to? tldr - support your blanket statements, gentlemen.

I recently came across the same problem as the OP. My car is used in a very similar fashion (lot's of HPDE and as a daily driver). The symptoms and sounds according to the video are also exactly the same and it's been getting worse over the last month or so. Time for a dealer visit.
I'll update once everything's settled. Btw, only mods on my car are RCE springs, Hawk DTC-60 pads/fluid and I run Yoko AD08 tires for track on some cheap tirerack 17's. Mechanically and otherwise bone stock.

Sorry, no time to do a video right now but it's definitely the DI seals. Took it to the dealer and that's what they came up with. Seals are on back order. Hopefully that's the extent of it. My car only has 16k miles on it. Gonna suck if I have to have this done at that interval.

How loud is this "Firecracker" sound anyways? what does it sound like while driving?
does it occur during the middle acceleration? or just when going from off throttle to on throttle? |

I experience a pop like sound, along with a slight shake to my car with it, right when I turn it on. It only happens when I turn the wheel completely to the right. Like literally, right when it starts up, you hear just one pop like sound. My engine also use to rattle when the symptom occurred but soon stopped after I added motor mounts. So Idk what it could be. Car runs fine no idle dips or anything Quote:
