Sounds like ur idle control valve isnt functioning. May want to look at that.

Do a compression check. Sounds like you might have a vacuum leak as well...

Any CEL's?

cant do a compression check til monday, im using gsr throttle body and gsr manifold. my brother adjusted the throttle cable so it doesnt die when its started. i pulled out the iacv and checked it out it was clean i also switched with my homies gsr and it still bogs. iacv it is not, if i can get a fuel filter for cheap ima change that out any how. hopefully i can get one for 8 bucks. i also checked the vacuum lines nothing looks like its off and cant really hear anything leak the instructor gave up on it too he said it maybe vacuum leak but then we couldnt find it. he said he does like hybrids(haterrrr). any how, i might have to chek the vacuum's again in a bit.

oh yea and the car doesnt bog as much in startup anymore until it warms up it starts going up and down really bad.

The ecu collects information from each sensor independently and uses it to calculate timing & fuel. If you have the wire(s) switched, the ecu is getting incorrect info, resulting in a horrible running car. Also, the Map & TPS are the 2 most important sensors you have (next to crank/tdc) so if these signals are messed up, you will know.

Sounds like the same problem I'm having with my car. Here's the thread:

I have gotten over my car being stolen . But Im not going to be taken so easily next time. That is why I bought a new security system. It travels at over 1100ft per second and you cannot out run it so bring it on "you must not want to live". My stuff may be material stuff but it does matter to me when it is stolen. You are not replaceable but I bet when your gone knowone will even miss you.
