Hey new here. I've looked all over and have found bits and pieces of what I think is my problem but I figured I'll ask to see if i can get a more specific answer.
I just bought a 2008 v6 premium convertible. The car runs and drives great except if I stomp on the throttle from a full stop. I can get to full throttle if its already moving without this issue.
What I've done:
I turned off the overdrive
Turned off traction control.
Floor it
result: engine failure. The check engine light and anti theft lights flash. If i dont let off the throttle the engine will go into limp mode.
I've seen reports of possible MAF sensor or fuel pump as being the cause for this. Needless to say its a brown out that i can't stomp the pedal.

Any thoughts or suggestions would be greatly appreciated
Thanks

You need to pull the code(s) from the ECU, but a blinking CEL is Misfire. When is the last
time the plugs were changed? Coil pack?

The blinking PATS light, there should be a pattern. Record the slow flashes, and fast flashes.

PATS may just need reset, you need to manually lock the driver door with the key
the next time you exit the vehicle. Not a for sure thing...

thanks for the advice 08'MustangDude,

Maintenance records dont list plugs being changed ever.
I'll pull the plugs and clean the throttle body out as well.
Replace the cheap stuff first i guess I was thinking my fuel pump was crapping out.

Also the lights all stop flashing if I let of the throttle before limp mode gets activated.

There have been issues with this, and most of them were MAF issues, wiring short, or
bad MAF. MAF has the integrated IAT as well...

Still need to have someone read the codes stored...

Agreed, without the codes all anyone can do is make a SWAG attempt to help you (Scientific Wild A$$ed Guess)

I'll get the codes checked today
Thanks guys.

Only code reported is P0607 which i got from replacing the battery I guess.

What the P0607 code means

P0607 is the standard OBD-II trouble code for an issue with the engine control module (ECM). The code suggests that the ECM is experiencing problems, such as power failure or memory loss, and thus may not be able to do its job properly.

What causes the P0607 code?

The control module performance trouble code can have multiple causes:

• ECM is faulty due to physical damage, the presence of water in the ECM, or corrosion
• Electronics in the ECM are faulting
• The ECM wire harness is misrouted
• Vehicle’s battery is dead or dying
• Battery cables are loose, unhooked, or corroded
• Vehicle’s alternator is malfunctioning
• ECM has been improperly reprogrammed, or has not had the software updated

What are the symptoms of the P0607 code?

The P0607 trouble code will usually be accompanied by the Check Engine Soon Warning Light. The vehicle may also have a problem starting, or may fail to start at all (though the engine will likely crank). If the vehicle does start, you may experience some engine issues, and the vehicle may even stall while you are driving. Fuel economy and smoothness of driving will likely be negatively impacted as well.


Check your battery cables for corrosion. Check your PCM/ECM that sits in the engine bay for loose or dirty connections.

Should be more codes than that with the blinking CEL...
