So I posted this in the engine section but no one responed, I hope soemone will help...

Latley my car has been having issues when starting after it has been sitting for several hrs and especially after work and in the morning. When I start her she seems like she is chocking and wants to die today after work it was the worst. She started RPM's went to around 2500k and then dropped to the point where she almost died I hit the gas a couple of times with nothing happening and finally she leveled out and ran fine. It is an 08 and only has 7000k miles on her so taking in is not a problem I just can't for a couple of days because I am out of town. Has anyone had similar issues?? Or any suggestions as to what the problem is, I dont think it is the fule because I have filled up at different stations since this first started but it just gets worse.

 

Checked your oil? Leaks in the diff/trans fluid?

 

Dirty MAF sensors

 

I had a problem that was VERY close to that with my last car that I supercharged. It was because it was running too rich. It was bogging itself down.

Have you done any mods to it? Throwing any codes? I, about once every couple weeks would throw a misfire code.

If it is because you are running too rich, maybe you could try unhooking your battery for a while and hooking it back up to reset the ECU(easiest way). Or maybe you have a shot O2. If those fry they can read wrong levels that cause your ECU to think you are running lean and start dumping more fuel, causing that problem.

I may be WAY off but I am just speaking for something that happened to me and has almost the exact same symptoms. Everytime I would start the car it would drop to about 500 rpms and if I didn't blip the throttle it would stall.

 

Maybe something to do with ur airbox.

If its a 08, take it to the dealer, Im sure u still have warranty.

NO mods! And yes I have warranty, just had the oil changed at nissan and of course "they" did not notice anything, I was just wondering if anyone had any ideas what the problem might be. Also wondering if it is safe to drive the car or if I am doing more damage to it!

Thanks everyone.

 

It could be a simple problem/fault with the auto choke.

See if gently using the throttle manually when you coax her to life helps. i.e. you are now overridign the auto choke. If it is the auto choke it will mainifest itself more prominantly when the engine is cold.
Don't flood it to start unless you can't get her to start at all.
