MIL blinks...

joseph you just saved yourself from me trolling you with your ninja edit. btw its "you're"

Joseph B

?? People need to be properly informed of what is happening with their car when the MIL blinks lol. The ignorance on this board is most amusing.

ProfessorDave

I think people are interested in the outcome. Nobody likes to see the owner of a new car (especially the same one we own!) have codes thrown and limp mode engaged.

I agree professor Dave.

If it is flashing then it indicates a critical fault, hence why the engine is in limp mode. The result can be because of a critical sensor failure (e.g. crankshaft position sensor, camshaft position sensor, VVEL position sensor) or because of a misfire. Obviously the first step is always to immediately read the code to determine the next step of diagnosis - the very first thing I said. System readiness test failure on start up will also cause the MIL to blink, but in a different fashion, 20 seconds on, 10 seconds flash. Sure in the OP's case it was a misfire event but for the purpose of general information I was trying to point out that the MIL light can indicate different things.

Rather than attacking other posters why not refer to the service manual with specific information? I don't think I fed misinformation to anyone, so the responses are unwarranted.

That response was much better than your first post Chris.

if that happened to me i'd freak out.. i'd be at the dealership before i could even post on this forum about it............

but noway its bad gas imo

optiontrader

I'm thinking the same about the gas. Worst I can imagine is the trucker dispensed the wrong fuel into the tanks. Mebbe he got diesel? I'd figure everyday engines would sputter or die with diesel in them. Would a Z's engine be different?

ok, I left my car @ the dealership this morning. they just let me go home without the car. and got call afternoon from them, they said still couldn't find what is the cause of misfire. but they think that its cause of computer problem... so need to order new computer (I think its ECU??) from japan. so i need to wait for 2 weeks to get it. and asked them to provide me a rental car. but they said no. and... they keep saying that it might not be covered under warranty, because i had car accident before. it was an year ago. and was front end damaged. I had to replace condensor and radiator. (Not the engine.) and car has been running great since then. Do you guys think misfire is cause of the accident?? and really think it won't be cover under warranty?? I was really pissed off that i heard that from dealer. I don't know what to do... should I call nissan canada if they say it can not be covered under warranty???

I've bought gas at that station in the past(not w/ 370Z) never had problems...guess the 370Z didn't like that gas

Morrey is where I take mine, they're alittle slow b/c their so busy but overall no complaints.

ChrisSlicks

Replacing the ECU seems a bit drastic, did they discover any other evidence to indicate that the ECU was misbehaving? Also I doubt that the ECU could have been damaged in the kind of relatively minor accident you are describing. I've seen working ECU's come out of total wrecks, they are pretty durable.

I love how quick the dealers are to pull the "your warranty is void" card. In order for them to actually do that they would have to establish some kind of correlation that there was unrepaired or hidden damage. For an accident that was a year ago that is going to be a pretty tough sell.

ProfessorDave

And the tough sell would have to be to your insurance company, since the dealer is claiming they've found previously undiscovered damage. I'd educate yourself about warranties a bit (lots of threads here, some with horror stories) and play hardball with these d-bags.

Keep us posted...

i encountered a similar problem today... while i was cruising on the highway about 100mph and when i was about to go in a junction maybe another 400m away, i put the gear to neutral. My intention was to let the engine breathe the incoming air to lower the oil temperature but suddenly the Zs' engine cut off, & limps on... brakes wasnt working normally, steering was hard to steer and the Malfunction light lit on. Got panicked, but eventually the car limped to a stop safely on the side of the road.. Tried restarting it and it was back to normal...

I wonder what made the Zs' engine died unpredictably? Any ideas guys? was it because i put the gear on neutral too soon after aggressive revs?? sudden drop of heat to the engine oil perhaps? i dunno?? Please advice.... Thanks....

Were you low on fuel? A complete engine cut like that has mostly only been experienced by people driving hard when below 1/4 tank. I don't think it has anything to do with oil temperature, this is not limp mode.
