Having problems with your 1990 Chevrolet S-10 Blazer ?
1990 full size blazer starts fine idles then dies
\015 I have a full size 1990 blazer with TBI injection starts up fine cold idels till it warms up or choke comes off changed fuel filter,fuel pump,fuel relay, & ECM it stays on at high idle even when warm when it goes to low idle it shuts off I turn key and I could hear pump run won't start until I put fuel in TBI it stays on until it goes to low idle\015
Sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know
