My S10 starts fine and idels great. I go to give it gas and it starts to bog down and will even die out. I have replaced the fuel filter and the fuel pump. I have also cleaned the injectors, and replaced the coil. The injectors are spraying plenty of gas. A year ago I replaced the disrtibutor modual. The truck is a 4.3 V with 248,000. Any ideas this one has me blown away.????????????
