SOURCE: my 2000 v8 toyota tundra suddenly lost power

Does this motor have the equivalent of crank-trigger ignition? If so, is the sensor A-OK?

SOURCE: 2004 Audi A4 misfire

it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.

Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

check your coil packs, my 2000 did the same thing but only on one. take coil packs off and relocate them to new plugs, clear codes and recheck to see if missfire "follows" moving coil pack

Initially change the Plug lead to get a result. Use a Long enough Plug Lead from any other vehicle, as a quick fix, and reclean the offending Plug before trying.
