light is still off but who knows

#1 I'm going to ASSume that the codes were P0123 and P0455? And #2 I'm going to assume that you got the codes reversed? If this is correct then the P0123 is for an open circuit in the TPS that allowed more than 4.50 V to be present at the sense circuit in the PCM. This would be a sure sign of a loose connection at the TPS, a bent prong inside the connector, or a failed TPS. The P0455 is for a large leak in the EVAP purge circuit. It says that yours uses a basic LDP with a vacuum switch and the purge solonoid to supply the pumping. Trace the large heavy guage vacuum line under the hood that runs over to a black solonoid. The vacuum line at some point will have a green test port cap on it, and it should tie into your vapor cannister which is a rectanguluar plast canister that was mounted under the hood on the passenger side on alot of them.

Ferm you are right on all accounts got the numbers mixed up sorry. well she is still acting up choking, stalling, spitting, sputtering. I am going to get a new TPS at advance today (if they have one) and put it on tonight. Looks like it is only two screws. pretty sure i got the vacum line thing taken care of. like i said i forgot to put one back on.

thnks

My check engine light has been on for about 2 years so I keep checking the engine and its still there.

You'll need to do a reset on it after replacing the TPS, so disconnect the battery for at least 30 minutes after replacement.
