Will somebody please help me i just pulled out my motor to replace the clutch,rear main seal and replaced all my vacuum hoses well i been driving it for 4 days now and since i first started it the idle bounces up and down 2000 rpm to 2500 i pull up on the throttle to lower it and it wont move it just bounces up and down sometimes when i drive it slow down and make a turn the idle drops real low and sometimes die and then it gives me hell to start. also can anybody tell what a iiac,iac and a map sensor is. thanks for the help i really appreciate it, its hard to see my car like that.

 

Have you checked the map senser?

 

how can he check it if he doesnt even know what it is...?

btw, the blue line is the start and end of the vac hose attached to it

 

the symptoms your descibing dont sound like the map sensor...unless your are also having odd colored smoke pouring out your exhaust? if so, its your map sensor

your high idol could most definitly be a vacuum leak, but im not sure about why your car dies after the idol spike...

 

If you pulled the motor there are countless possible connections that could have been missed and cause your problems.

Do you have any ECU codes?

 

PLEASE tell us you carefully marked every wire and hose (especially the vacuum hoses) and took good digital photos of your disassembly.....?

Because like Dave says, there are COUNTLESS ways to make a minor mistake when re-connecting everything.
About all you can do is to take off enough stuff to get to your rat's nest and start tracing everything, making sure it is all hooked up right.

 

If he just pulled his motor, replaced the clutch and rear main seal and did a vac hose job himself, he should know where the Map sensor is located. Otherwise he's in a world of hurt. A search will turn up lots of info on the map sensor and possibly some pics.


later

 

first i would like to say thanks for all the help i appreciate it and for the map sensor how would i check it and is the black check valve a one way or should i be able to blow through it both ways.

 

The black piece under the map sensor is a filter, so yes you should be able to move air thru it in both directions. It has an arrow so you can keep track of the 'clean' side.
