Toyota MR2 bad injector
A Toyota MR2 is having problems after an engine replacement, fault code P0304 Cylinder #4 misfire detected occurs. The garage swaps several components but does not manage to fix the problem. Measurements with an automotive oscilloscope are required to find out that the fault code is somewhat misleading and the problem is not with cylinder #4
