new ap1 owner need help =( p1129 and car max out at 55 [email protected] 6th gear

1st off. i am vincent from chicago the windy city and recently purchased this sexy s2000 but ran into a few problems =( any input would be awesome!

i got a code p1129 earlier this week. so i did a map whack and got a new map sensor...

new problem had occurred after i did map whack and got new map sensor.
p1129 is still there.. i did a ecu reset and also did the -hold the rpm at 3000 till it get warm thing as well-

The car would run perfect before it reaches normal temperature.. once it hits normal tempt. this is the new symptoms:

1.) every gear have a very low max speed. 1st(20mph) 2nd(25mph) 3rd(35mph) 4th(45mph) 5th(50MPH) 6th(55mph)
2.) if i try gassing pass the max speed for each gear. gas would cut off and cause the car to choke a bit..
3.) when it does this, i turn off the car and start it again and it would run normally...
4.) it only does the max speed thing once the CEL comes on..(p1129 manufacturing control air metering code i got from the obdII reader)

specs and mods:
- ap1 117,xxx miles
- lightweight flywheel possibly 6 pucks clutch
- Laskey head (valves, p&p, springs)
- headers and full exhaust
- AEM code air intake
- aftermarket radiator
-- pretty much it



any input would be great.. thanks in advanced!

problem solved!!

verdict:
- low rpm runs shitty low rpm, no idle problem, runs great higher rpm = vacuum leak...
- in my situation was the throttle body gasket! there was a leak.... =P

how to test for leak: get a starter spray... spray a little around intake manifold area. if rpm goes up.. u have a leak!!
