I jus purchased a 1996 pontiac bonneville and it has been giving me the blues... but today my check engine light popped on and began to flash off and on. I went to auto zone to get a reading and it said i needed a TPS sensor which i already replaced as well as spark plugs. what could be causing all these problems plz help!!!!

A flashing SES light is a misfire, P0300 threw P0306. This can be caused by a bad spark plug, bad plug wire, bad coil, or bad ICM. Need that code and we can help narrow it down.

yeah what he said and welcome to the forum

welcome to GMF
x3 on what dan said, less than a month ago i had flashing SES and it was a bad coil

well the codes im gettin is po122 and po033

P0122 is TPS low voltage https://www.gmforum.com/showthread.p...68#post1390952

A bad TPS can cause odd problems.

ill post in your other thread

well i dnt know if the person who put the first one on set it to correct voltage.. imma gurl so im kinda lost lol. but woud those two codes cause the car to cutt off from time to time also sumtimes when driving it wont switch outta first gear could the tps cause this or is that sumthin else

Yes an out of adjustent TPS would cause the issues you face...It is very easy to install i reccomend takin it out and making sure its installed properly

wow havent experienced that and hopefully i dont it seems like every person i know with a bonneville is experiencing problems... its the darn computer it throws everything outta wack..
