I hate to keep posting problems but this truck has more noises then a cheap hooker. (not that I would know, someone told me :rolleyes: )

If shes hot (my truck not the hooker) and I go from a stop light it pings like a gasser. Its not the pilot injection as it only does it when 1st pushing the fuel pedal and at low rpm.

Its also taking about 1/2-3/4 of a second longer to start sometimes.

I dont see any white smoke. Its still has the surging idle only it does it hot/cold now too (very hot/very cold) and it will surge like this rmmmSURGErmmmmmSURGE when hot ideling. Before it only use to do it when warm (not hot not cold).

Any ideas?
