SOURCE: I have a Toyota vista 1998 model. It's hesitating
replace the ingniter~~
Testimonial: "Thank you very much for the help. "
SOURCE: codigo P1300
The code that is of main concern is the PO300 it indicates random multiple engine misfires, normally there are other codes such as PO301/PO304 etc which indicate what cylinders are misfiring, this engine does not have a distributor, it uses individual coil packs, one per two cylinders, these coil packs cause the problem, usually it is only one out of the three.
They are located under the black cover
you would have to try switching the coils around to different cylinders
SOURCE: i have error codes of p1300,p1305, p1310, p1315,
P1300 = ignition system malfunction (#1 coil/igniter circuit fault)
P1305 = same as above but #2 coil
P1310 = #3 coil
P1315 = #4 coil
SOURCE: How do you fix an Igniter Circuit Malfunction -
The problem 95% of the time is an ignition coil, if you do not have special equipment, your only tool is common sense, disconnect plugs from spark plugs, remove spark plugs,now insert the plugs in the wires and set them together touching metal ground them,
Ask somebody to crank vehicle one of those wires or 2 of them if the coil is bad wont fire or the spark will be weak and orange, blue is ok. Follow the no spark or weak spark to the coil, now swap coils , repeat the same procedure if the problem follow the coil to the wires that were ok before the problem is the coil if the problem is still in the same position the problem is harness wires or computer.

p1300 is random misfire. It can be caused by a bad O2 sensor, in some cases.
Good luck on this repair.
