I have a 4.7 tundra wouldn't start the other day ended up changing spark plugs and fired right up but was missing on cylinder 4. Noticed bad seal on the coil replaced and fixed the miss. It showed codes for o2 sensors pedal position sensor and magnetic clutch also. My issue now(which it's been doing for a while) is I can hit the gas and at only 3000 Rpm it sounds as if it's redlining. Another thing it's doing is I have to let off the gas or it will not shift up. I'm not sure if this problem is related to one of the codes or the tranny. Any suggestions or someone that's had the same problem before have any suggestions?
