I have a 1991 s10 pickup woth the 4.3 liter fuel injected and I have replaced pretty much all the pars I could thing of for a rough idle and still can't figure it out. Just replaced the coolant temp sensor thinking that might fox it and still nothing. Also the pickup will not warm up past about 100 according to the temp meter. What do I do !!!
