Weird MSP situation

[03.5MSP]

Well when i drive my car I notice that the car will drive nice, and it will pull good. But as soon as the temp reaches the middle and the car warms up it become a totally different car and acts like s***. THis has been occuring ever since i can remmember, & I know that our cars go from closed to open loop. So what is happening, and when i install my microtech will the car still do this?

Also when i installed my PG intake mani, there was one green circural piece that was attached to one of the vacuum lines. I never put that green thing back on the car since i replaced all the vacuum lines. I saw a pic of it once but im not sure what it is, and if i need it. Ill try to find a pic of it.

Thanks for the help,
Marko

explain.. "acts like s***"

I press gas and it goes no where. I just see the egt gauge go from 600f to 1000f in like 2 sec. It just feels like it has no fuel and or air. Could the msp hessitation really be that bad? What does the ecu do when it reached about 149F? I know something with open and closed loop happens.

So I guess my bogging and or crappy drive ability is caused by the msp ecu, when it goes into closed loop, and decides to just inject a s*** load of fuel. Im pretty sure the LT10 will take care of that.

Now onto the little green circular thingy. he he

what mods do you have and when did it begin?

I have aem cai, PG intake mani, mam exhaust mani, perrin fmic, corksport spipe, apex dp, greddy catback. It started to get more and more noticeable as i installed more and more parts. But only reticently have i been able to monitor the egt temps.

Do you have any pics of how you routed the vacuum lines for your 626 mani?

im having the same problem,,, wen my car heats up it feels like there is barly any power,,, some times its really hard to get threw intersections without gettin T-Boned,,,

does this problem go away wen u keep it out of boost??

because it does for me but wen ever i put the car into boost there is barly any power

and now i noticed that im boosting at 8.5 were i should onlybe running at stock psi and i vacuum at 17 - 18

Troubleshoot your Engine Coolant Temperature (ECT) sensor with a voltmeter/ohmeter by following the instructions in the manual:

The MSP (like most OBD II) will advance timing, lean or enrich fuel mixture, cut spark, etc. based upon the resistance the PCM sees at the ECT sensor.
