ok so my sisters car likes to sputter alot and everything and is still under warrenty, so we took it to the dealer 11 times now!! and it still does it, and last night on the way home, the car was missfiring horribly, and we pulled over and restarted the engine and it ran fine, so we pull back on road and accelerates right up to 50 mph and just sits there, and the gas is all the way down, so we drive home like this and when i got home at 3 in the am this morning i put my code reader on it and i got all three of these......


p0300 random misfire
p0133 o2 circuit slow response (Bank 1, Sensor 1)
p2096 post catalyst fuel trim system to lean Bank 1


the dealer has replaced all kinds of sensors, dropped the fuel tank new fuel pump and filter everything.. so any ideas from you guys, taking it back to dealer again tomarrow...

oh and we have takin it to 3 different dealers now.

Okay.. it seems like her car is doing all that because of misfires. Random misfire means, any cylinder, no particular reason. So this means, your sensors are not giving the ECU the right information, and since its alot of random sensors even after being replaced are not working properly.. means the sensors are not getting the right power supply. which is all leaning me towards the Engine control unit. So, there ya go

already replaced that same thing. they think the catalyst converter might be plugged they are looking into it.. isnt there a lemon law on this?

Have you tried replacing the cam position sensor?

It has its own code P0341. and It doesnt do all those symptoms at the same time. Possible misfire, and no start is the symptoms of a bad CS position sensor.

dealer is giving her a trade in for what she owes on the car. which is 7500

What a ripoff...... so all the money she spent for the monthly payment are GONE TO THE WIND?........ seriously ripped her off.
