Idles higher than ever/check engine light on

Get the code retrieved , the code will indicate the area in which the problem lay. The idle speed may be high due to a failed idle speed motor or the computer in your car may be compensating for something else. foolish to speculate without retrieving codes and doing basic diagnostic tests.

spray carburator cleaner at number cylinder intake while motor is running (its behind power steering pump and block)if it is leaking it will bog down when you spray # intake port. if if bogs when sprayng....change intake manifold gasket...20.00 at parts store. another symtom is cylinder misfire on cylinder 1 hope this helps oh 400.00 for mechanic 4 hrs work or 20.00 if you do the work yourself

check for intake gasket leak. spray some brake kleener around the intake, see if it idle down
