Hey guys, this is my first VR4 it's a bit of a mess I that picked up from a friend. I just replaced the transmission fired it up yesterday and it ran. I did adjust some settings on the MAF translator while it was running (wrong injector size was previously selected). Went out this morning to start it now the motor spins but it won't fire after 4-5 tries I will get a giant back fire. I know I am getting spark out of the wires and with the backfire I assume Its getting fuel. It seems like a possible timing issue? I do have a CEL I did hook up a LED to the test port but I either don't know how to count or I am not making sense of the flashes. I added a youtube link with the light. Any ideas?
