So far i have
Cleaned MAFS
cleaned throttle bodies
swapped plugs
swapped coil packs
emptied the gas tank and put new fuel in it
O2 sensors are getting the correct voltage
Camshaft sensors also get correct voltage

So since i last Posted i changed The plugs...put a new fuel pump in and new air filters.....
i relearned the idle throttle positions and ECU
the car now runs and idles fine...when i drive it and apply the throttle it bogs down

HELP
so i posted on here recently with little help...so let’s try this again
i got in my car one day to drive it and it idled horribly and would die...got to the point where it wouldn’t even start
here’s a list of everything I’ve done
new fuel pump
new plugs
new coil packs
cleaned MAFS
cleaned throttle bodies
new gas
new air filters
relearned the idle,throttle position, and ECU
So now the car fires and idles right...but when you drive it and the throttle is under load it stumbles on itself...
any suggestions? Cam sensors and CTS are my next purchases

In the future, please go ahead and just bump your existing thread, especially since it's only a few days old. Dup posts are NOT going to get you answers any quicker than a refreshed original thread and causes confusion. People are busy, you cannot always expect an immediate, right now answer. Thanks.

The people that have responded on this thread are always very good sources of information - don't whine when people either don't know the answer or won't attempt a virtual diagnosis without putting hands on it.
If you can't respect that and are expecting instant gratification and results from your posts here, take it somewhere else.
