Itook a few pictures of the throttle body/manifold well the first part Im holding in my hand It has two bolts that hold it on, well I noticed one of the bolts was missing Im thinking that could cause it not to run good, Well what is that piece Im holding in my hand? And which sensor on there is the ISC, I have a picture of a blue sensor and a black one? Im thinking of doing a overhaul on the the whole injection system? is this diffucult and is there topic with pictures that shows you what to do? Thanks. THis injection system is off a 1991 geo metro automatic. Thanks for all the help :cheers

THIS IS THE THING THAT CAME LOOSE AND ONLY HAD ONE BOLT ON IT, IT SINCE IT WAS LOOSE IT WAS PROBALLY TELLING THE MAP SENSOR TO SEND MORE GAS, SENSE IM SUSPECTING IT WOULD CAUSE THE PRESSURE TO LOWER?

EGR is in your hand, yes that would make it run bad.

First pic is your EGR. Get a gasket and another bolt.

2nd pic is your EGR solenoid to allow it to be activated. Likely it's fine.

Last picture is your idle speed control solenoid. All it can do is raise your idle.

what is the compression on that engine? Looks like you have a lot of blowby from the throttle body pics.

I jsut rebuilt it 8000 miles ago and it is 190 on all three, before I rebuilt it there was a lot of blow by but I never cleaned the throttle body.
