Engine Performance problem
1999 Chevy Blazer 6 cyl Four Wheel Drive Automatic
About 2 weeks ago the blazer started to to take longer to start up. It used to start right up. Now it takes a few seconds for it to finally start up. Sometimes it will start right up with no problem but 80% percent of the time it takes longer to start. Sometimes I have to stop and try a second time and them it will start up. About 5 days after this started to happen I noticed a problem with the RPM's. After I would start it up I would put it into gear and the Blazer would take off on it's own without me pressing the gas. If I let it go on it's own it will go up to about 30 mph and the RPM will stay around 1200 rpm's. The only way I can make the rpm's go back down is I have to press on the brakes until the rpm's drop below 1200 and then it's fine and the rpm's drop to about 6,000. But if I press on the gas and bring the rpm's above 1200 and then take my foot off the gas pedal the rpm's will come to 1200 and stay there and it will keep going by itself until I press on the brakes and make the rpm's drop below 1200 and then the rpm's will drop to the normal idling rpm. I don't care for this because if your not paying attention when you put it into gear and as soon as you take your foot of the brakes it will take off by itself. Seeing that both of these problems with the RPm and the longer starting started pretty much around the same time could what ever is wrong be causing these two problems. Any help with these two problems would be greatly appreciated. Also I replaced the fuel pump 5 months ago and replaced the spark plugs and air filter at the same time. Also the check engine light does not come on and I have a scanner to check for codes and there are no fault codes at all.
have the same problem?
