1999 accord vtec, givin me guff!

as i said,…it was in limp mode, got it cleared and its workin fine now, not sure what caused it, but they think sumthin got messed up in the accident (obviously), but when it was repaired, meaning wires, and everthing else got put back where it belonged it corrected the original problem , the only think left was to clear the ECU. damn cars…
