Statement & Question, I have a 1992 S-10 with a 1970 something LT1 stuffed into it. The truck has been sitting in my garage for about 5 years with a semi annual start up. Saturday I went out and cranked it up, it smoked, sputtered, coughed and ran like someone filled it with diesel. I recently put 5 gallons on high test and stabilizer in it. I pulled the plugs and changed the wires. still coughing, sputtering, smokin. Any suggestions?????
