QuestionQUESTION: I have a 1997 Plymouth Breeze, a few months ago the Check Engine light turned on. Using my DRB I found that the error code is P0132 (Upstream O2S shorted to voltage). I replaced both the O2 sensors, and reset the Check Engine code. The car starts and idles, but it lacks power for the first block or two, and the engine will almost die during acceleration. When you give it more gas the car will almost die and then take off like a shot. It yo-yos like this when driving. Even after changing the O2 sensors, I am still getting a Check Engine indicator after running for 5-10 minutes, and the code is still P0132. Also I have checked the sensor resistance and socket voltage as indicated in the service manuals. Any ideas on what is the real problem?
ANSWER: what engine size 2.5 v6 or 2.4 4cyl???

QUESTION: It's a 2.4 4cyl. Sorry for forgetting. Overall it seems like it's not getting fuel. I borrowed a fuel pressure gauge to test pressure, after relieving fuel pressure I attached gauge to rail. When I turn the key on the pressure goes up to 46 PSI with the engine running the gauge bounces between 46-50 PSI.
AnswerFuel pressure is good at 46.
U put new up 02 so that leaves wires.connectors,pcm.
Unless u have a Scanner that can show 02 volts u wont be able to tell with 100% what the real issue is. All i can say for u to do is look at the connectors for any green monkey in there or wires touching together.
