Hey, I just put a f22a6 in place of the blown f22a4, I kept the a4 intake because the injector harness plug ends were different. Anyways, the problem I'm having is when the car sits for a couple of 3-4 hours, the car bogs down, it'll start moving like it should and then right before it shifts into second there's nothing, I push the gas pedal to the floor and nothing still, a couple seconds later it will take off, upshift, downshift, then smooth out, same thing right before third also. After driving around for a while it doesn't do it anymore and drives perfect, like it 's warmed up or something(I live in Vegas, so really, nothing needs to warm up, it's hot as hell outside). Check the codes, I got 1 and 43, so changed the O2 sensor, and now thats ok. Is the Trans going out? This is my first Honda/front wheel drive, so any ideas or help would be great. Thanks in advance, oh yeah its a '91 ex coupe w/automatic.
