untill i hit about 4k the car seems like its not getting the air fuel mixture it needs, i really need to pick my self up a ratio gauge soo i can fine tune my FPR but im cheap and only bought fpr gauge, i just slopped a new O2 sensor in there , i did also have a leak in the thermostat housing which i think may have effected it cause the b20 has the ECT sensor right in the thermostat housing and could have had a air bubble and read engine temp wrong screwing with the mixture... o well gotta wait 24 hours for sealant to cure till than i hope either of them was the fix.

Did you have any CEL's?

A autometer a/f guage won't tell you **** :-)
You need whats called a wideband oxygen sensor to really tell whats going on.

i was throwing a o2 sensor code , but now im not but it seems to be loping at idle really slow no5t like a vaccum leak drops to about 750+ than rises to about 1500 in about ten seconds a cycle

took the words right out of my mouth, spend liek 300 and pick up a wideband


btw remember you drive a honda. dont expect gobs of torque

but a b20 still has torque, i mean it LAGS like this is not by any means normal almost like the throttle cable isnt being pulled till i give it full throttle

I like the fact that you mentioned vacuum leak. check for them. it's possible you have one since you were playing with your FPR.

has a timing belt been done recently? does it idle roughly aside from the surging idle? check your base timing.

Check your timing.

nah i just re did timing, new belt neew water pump the whole sha bang, and yea the timing is perfect

could TPS be the cause of these problems by any chance&gt;? cause when disconnected it lags worse but in the same way untill about 4 grand she starts picking up

R6E6I6D

could this b caused by map sensor going bad&gt;? my buddys accord did the same thing b4 and the map sensorwas bad

Found vaccum leak in the top part of the aem fpr... when I went to change diaphram which i figured shitted out turned out it was the stupid metal connector the vaccum hose connects to soooo i dripped a bit of gasket maker **** on the out side of it and with a vaccum pump fromautozone pumped it to about 10lbs of vac and it sucked the gasket stuff in and i let it dry now it holds up to 25 In/hg lbs whatever
