Hi, fighting codes: p202, p300, p0301, 302, 303, p01132, p1152.
car had intermittent 'miss' w no codes. Then it went to the codes I listed.
found nothing noticeable visually, changed the injector with a new one. No luck.
its a short run to the ecm and harness looks to never been disturbed. The charts say either wire fault or an ecm issue.
is this common?

Misfire codes are hard to find it can be any sensor and not necessarily an ecm. Have a pro check for this the 1132 and 53 codes can be a vacuum leak which can also cause the misfire codes check the intake gasket and or isolator bolts as it may be leaking from there causing all of this.

56) KOEO, KOER & Continuous Memory DTC P0201-P0212: Check Fuel Injector & Circuit Resistance
Turn ignition switch to OFF position. Disconnect PCM connector (s). Inspect connector for loose, damaged or corroded terminals. Repair as necessary. Use injector fault PID noted in step 5) to determine fuel injector circuits that require testing. Using a DVOM, measure and record resistance between suspect fuel injector circuit and VPWR circuits at PCM harness connector. See PCM FUEL INJECTOR, PWR GND & VPWR CIRCUIT TERMINAL IDENTIFICATION table. See Fig. 4 or Fig. 5. Resistance should be 11-18 ohms. If resistance is not as specified, go to next step. If resistance is as specified, concern may be intermittent. Go to TEST Z, step 1). If unable to duplicate concern, replace PCM.
PCM FUEL INJECTOR, PWR GND & VPWR CIRCUIT TERMINAL IDENTIFICATION
see pics for where to check also check for eger plugged, vacuum leak ignition problem compression, etc. Check O2 fuses, evap system can be any of this. No it doesn't seem to be common with a 202
