Hi Guys
while cruising around in summer time my car sometimes shuts down in the middle of road and it sounds like its missing on fuel, i changed the fuel filter, changed the fuel pump, changed distributor module, still feels like its going to happen when in summer car gets hot doe to engine heat and weather but when it cools down it starts back on and if you wondering what it sounds like when it shuts of its ( bhap bhap bhap bhap and boom shuts off and when i start back it starts but when i accelerate it does that bhap bhap thing again and goes back off until it cools down. Relay is the last thing to me or clean the fuel tank or change fuel lines? any suggestions would be appreciated. Thanks
