Starts normal runs about 3 minutes then dies, restarts normal and if you drive car before dies but when you slow to idle dies again, no codes shown, any solutions???

 

Please verify what tool was used to check codes. A generic obd reader can't unveil all crucial codes. Without more information we are guessing. There is help here so please participate as suggested.

 

1eapplebaum thanks for reply! Used Ross tech. I need to further explain. 1st got low voltage on info screen. Checked accessory battery and found 11.9 v so replaced it with new. Had several electrical faults, but like others the got fixed. Then after replacing battery on drivers side, car would start at regular warmup higher rpm and then when it slows to normal idle it stumbles and then dies, like it runs out of fuel. It will then restart normal and you can drive and runs great. When I stop and restart, same thing happens. Took to local shop for Bentleys it ran fine driving there, but it still has same symptoms . No codes thrown, and he says when he drives around block after starting it and having it die then restarts it drives fine billy dies when he gets back to shop and goes to idle then dies. They are still trying to figure it out.
Please advise- thanks in advance.

 

Just to offer my 2 cents. I would start with fuel management (filter, lines ect). Check anything to do with the Mass Air Flow too. Again, Just my 2 cents.

 

Hello @L356er ,
I had responded to you late last night wee hours of the morning, but my post is gone...

Anyway, my questions were the same as others, specifically as to Ross-Tech, so good to hear that you are using RT.

My next questions had to do with any recent history of the vehicle, how long have you had the vehicle, any recent repairs that have been done that could be the cause of the issue, any abnormal sounds from the engine bay, such as vacuum leaks, or intake air leaks, as previously asked by TJ, the MAF's, their hoses and or connectors, have you checked all air intake tubes to from turbos, intercoolers, air filters boxes, etc.

Also, with the Ross-Tech, have you scanned both engine ecu's for faults ?

Batteries, just for clarification and to all be on the same page, have you checked both batteries, the house (main) on the left, and the starter battery on the right after you installed the new left side battery, is the right side weak, therefore draining your new battery, I have had my GT automatically go into emergency power mode (parallel switch) when either of the batteries were low, also check the voltage of the new battery, I have received brand new batteries that were way under charged for time on the shelf, or some numbskull putting new batteries on the concrete floor, so check your voltage on both, also see what your alternator output is.

Johnny thanks for reply. Have owned for 4 years no problems, have had no issues until now, has been an excellent vehicle. Shop has car now so can’t check anything. I have scanned several times no faults show up for engine. That’s why it’s so odd.
