I recently got my car back on the road after an accident. I have had this swap now for 3 years and all has been good. Now once my car heats up it begins to bog back fire and miss. Before that the car runs strong and above like 4000 rpms bogs and continues to then get worse. Also if the car is shut off for say 10 min then started back up the problem is 10 times worse. At idle the car is great but when given gas in neutral or when driving the problem occurs.

Changed
coolant temp sensor

Checked
tps
grounds
plugs white at tip with black charcoal at base
timing without light
o2 sensor wires

everything is how it was before the crash and now it runs like shit any sugestions of what else to check
