1988 toy pickup runs great when engine is cold when it warms up and engine idle drops to give or take a few 900 rpms it runs really rough. new fuel filter new sending section all new injectors topical egr valve new brain box adjectives proper electrical voltage (olms) at injectors have done everything even read hanes book cant figure it out checked adjectives vacumes and lines no holes all ok
Answers: you say you (checked) the vacuume lines? i would put spanking new lines on anyways.there is also a vacuum guage you can hook to any vacuum port.to actually check how much vacuum you enjoy.another thing i would check is your bolts on your intake manifold,to manufacture sure they are tight.when its cold and the rpm's are up,it's getting the right amount of air and fuel mixture.you might want to do a compression check.you might have a bent,or leaky tap , but i'm still leaning towards a vacuum leak. thank you!
