98 intrepid hesitates

my check engine codes are reading fuel system too rich in bank 1 and 2. i changed top o2 sensors no help . now sometimes (usually in the morning) she will hesitate to move when i step on the gas, and its not revving high like a tranny problem. its like when i step on gas she loses her breath.also sometimes she will be choking in the morning and then rev high before idling down , i put some fuel cleaner in but it didnt help either.and what does a tuneup consists of since there are no wires or cap and rotor?

I believe just the spark plugs on that one,the fuel filter is in the gas tank(part of the fuel pump).For spark plugs go with champions,the best spark plugs for Chrysler products.Did you put in a cheap fuel cleaner in it?If you want to try fuel cleaner,try Lucas and Lucas is the best fuel injector cleaner on the market.Just pour in a certain amount in and you can find Lucas at certain autoparts stores.It sounds like the camshaft position sensor is bad,a common problem

thanks i`ll change plugs with your suggestions and by coincidence i did use the lucas cleaner , how about that filter, do i have to change the pump?

You do not have to change the fuel pump if it is still good.Chrysler put the fuel filter making it the part of the fuel pump in tank because no one changes the fuel filter underneath the car.You have to replace the whole fuel pump to get the fuel filter.

hey does anyone know where the camshaft position sensor is?
in the timing casing or on the outside of engine?

It is front of the timing cover,driver's side.All you need is a 13mm socket with a ratchet to remove itBefore pulling the connector,there is a red plastic tab holding it in place and get rid of that red plastic tab.

okay, replaced plugs ,filter ,pcv and camshaft sensor. my car stills stalls whenever it feels like it. although its more frequent now (once a day). the only code i get is 0172 (system too rich bank 1). do i just replace o2 sensors, because im not sure if that would cause stalling. and if other sensors were bad wouldnt i get codes for them? and if fuel pump/filter were bad wouldnt i get codes for that?
