Speed not dropping
I have a problem with my 99 blazer when i take my foot off the gas the speed & rpms do not fall rightaway i have to brake almost to a stop for it to come to an idle @700 rpm .I get a 507 code so i changed the iac & cleaned the tb & EGR realy good still does it.My next step is the tps ,but would'nt i get acode for that?
