I have a 96 oldsmobile ciera sl 3.1 I
keep getting code p1406 and p0122
and p0123 replaced egr and it says my
tps is good what do I do???
the code tells you where the trouble is not what to replace , a sensor of some type directs the egr through the computer probably , start from a source not in the middle of a system
Where do I start ?
Also after putting back on the tps it started going on its own I didn't have to give it gas and then it would shift Till 35 mph then after a short distance it would bogg down and die
what are the code definitions , see if the injectors are operating normal , , they make a noid light for that , take them out and see what they look like , one might be stuck open
check fuel pressure , some vehicles are particular , just having it won't do
