Question about 1993 Chevrolet S-10 Blazer
I have a 93 s10 blazer. has a 4.3 vtec.When i start it up it seems to run fine, and it warms up (about 150 degrees) it starts to miss and act up. If i drive it, it hesitaes and sputters. if i hold it to the floor it will take off. But just for second. After it gets to operating temp, the engine light comes on and it runs like it should. I heard a vaccuum leak and sprayed carb cleaner. It idled up.... thus a vaccuum leak. I looked at the egr valve and one of the screws was backed off about 1/4 inch. i tightened it down and took her around the block. Ran like it should. thought that fixed the prob. the next day it was doing it again. PLEASE HELP
I had a very similar problem with my 93 S-10 Blazer. I thought it was just cold blooded. I'd start it and it would idle so rough and spit and sputter and it seemed as though the fuel was dumping right out the tail pipe! I placed the computer on it as my engine light finally came on but all it said was that the exhaust was rich. Well I know that! Thanks computer. So then I heard about a product called "Seafoam." It will clean the engine of carbon build up. There are three ways to use it, let the PCV valve **** it up, add it to the oil, or add it to the fuel tank.
I pulled the PCV valve out of the valve cover, removed the valve from its stem. turned the engine on then I reved the engine a bit from the throttle body while I placed the PCV stem inside the can of seafoam. While the can is being emptied you will see and SMELL a huge white cloud of smokey fog coming from the tailpipe. As soon as the can is empty let go of the throttle. If the engine does not stall on its own shut it off. Let it sit for 4 or 5 hours. Then start the engine.....it may start a bit hard....and PRESTO!!! I was skeptical of this product as there are so many out there that claim to be the best but this one actually works!! My truck now runs and idles like never before. It even increased my gas mileage considerably. I'm going to wait another week then add another can to my full tank of gas so it will do a job on cleaning my injectors. This can of seafoam cost me only $11.00 dollars Canadian. Thanks Seafoam!!
