:1993 GS300 battery light is on , it misses at idle and acceleration. Last week heater hose broke soaked the engine I replaced the hose , replaced thermostat and radiator hose,put in a new alternator,,put in new disturber cap and rotor , plugs are new, battery is new ,put sea foam in gas tank, to clean injectors need help at wits end can not figure out the missing and my battery light on .
.

 

did you clean the body grounds?

 

under the hood,there is a diagnostic port,take a piece of wire, strip a bit of each end an plug one end into T and one into E1 than go inside of your car turn the key on and off about two times, than put the key on and watch the check engine light it will flash fro what ever number of code your getting,ifs misfiring it will put out a code. you can look up the code numbers online.

here they are any way

Code 12 and Code 13 Rpm signal circuit fault
Code 14 Igniter signal circuit fault
Code 16 ECT control signal fault
Code 21 and Code 28 Main oxygen sensor fault (for ES300; SC300 & GS300 models)
Code 22 Coolant temperature circuit fault
Code 24 Intake temperature sensor circuit fault
Code 25 and Code 26 Air fuel ratio fault (for ES300 & SC300 models)
Code 27 Sub-oxygen sensor circuit fault (for ES300 CA & GS300 models)
Code 31 Low airflow meter voltage (for ES300 and GS300 models)
Code 32 High airflow meter voltage (for ES300 model)
Code 35 Barometric pressure sensor circuit fault (for GS300 & SC300 models)
Code 41 and Code 47 Throttle position sensor circuit fault
Code 42 Vehicle speed sensor circuit fault
Code 43 Starter signal
Code 51 Switch condition signal fault (for ES300; GS300 & SC300 models)
Code 52 Code 52 and Code 55 Knock sensor circuit fault
Code 71 EGR system circuit fault (for ES300; GS300 & SC300 models)
Code 78 Fuel pump control circuit fault (for GS300 & SC300 models)

good luck

 

If your distributor is leaking oil it will usually leak directly onto the alternator causing the battary light to come on. You may have a bad alternator again. Also check the your connections on your alternator.
Not sure about the misfire. Maybe low voltage, bad computer, another leak etc.
