97 Sportage Engine Missfire Codes

[MSPRING]

I have a 97 sportage auto trans 4wd that is running rough. While driving sometimes the engine bogs down. If I let off the accelerator a little it gains power but the clutch in the auto transmission seems to slip making the engine rev high. Once again if I let off the gas pedal just a little the clutch seems to catch and it starts to accelerate again. These trouble codes are being displayed in my code scanner:

PO343- CAMSHAFT POSITION SENSOR A-BANK 1 CIRCUT HIGH INPUT
PO141- O2 SENSOR HEATER CIRCUT
PO301- CYLINDER 1 MISSFIRE
PO300- RANDOM MULTIPLE MISSFIRE
PO304- CYLINDER 4 MISFIRE
PO140- O2 CKT NO ACTIVITY
PO107- MAP/BARO CIRCUT LOW INPUT
PO302- CYLINDER 2 MISSFIRE

I would appreciate any good advise.

I would start by addressing the missfire codes - check the spark plugs and make sure that they are gapped to 0.75mm (0.03") and check the plug wires and coils.

The plugs, wires, and coils are new. But I dont think the recommended
gap is .03. I will check the manual. I think the problem might be the camshaft position sensor, chassis acceleration sensor, or maybe wiring.
I think it is strange that letting off the gas pedal a little triggers the trans to shift and the engine to gain power.
