my idle in my 94 del sol keeps jumping for 1000 to 3000

its a b16a motor, and i've replaced the IACV what else effects the idle

 

Its probably your fast idle valve.

 

there is no fast idle Value on this manifold

could it be any other sensors that are making it ldle wired

i also replaced the Head gasket,manifold gasket and the throttle body gasket

so i know im not leaking any vacuum

 

Take brake cleaner spray it on your gaskets and hoses anywhere it could have a leak.If its leaking when you spray it on there it should idle fine

 

i've checked all the vacuum lines and nothing is leaking, still crazy ldle

anyone got any clues?

 

Ive seen felpro manifold gaskets fail after doing head gaskets so after the first couple i seen with vacuum leaks i started using honda intake manifold gaskets only, torqued to spec btw . Spray carb clean on the gasket (between the manifold and head...) and also on the tb if you come up with nothing take it all apart and have a look maybe you made a mistake on the install. Nobody is perfect....

Live and learn

Let me know the outcome of what ya found

 

cool will tear down the motor tonight, and see whats happening to the gasket

 

status?
