Help!!! SR20DET idles high and runs like crap!
 

As the title says I just got done with my swap. The car idles at about 2000 rpm and it bogs down really bad when you drive it. I checked the MAF and I am getting power to the plug but when I unplug the stupid thing with the engine running there is no change. This morning I tried to check the ECU for codes but the light does not blink it just stays lit up. Any ideas???? I also checked the voltage to the MAF is 12-14 volts, but I'm not getting anything on the signal wire. Bad ECU???

vacuum leak maybe?

yea check all vacuums and make sure your throttle cable is adjusted properly

12to 14 volts bro......... you sure that your getting the signal and not the power source., the actually signal wire voltage is not that high it should be in the neighborhood of 1.5 to 1.8 v or so constant

I checked that, my hotpipe was leaking like crazy so I tightened them. Throttle is adjusted. Not much change here. Maybe timing is a little off???
Chris

throttle position sensor?

can you give more detail of when your cars messes up and how it sounds etc..

for example if it happens when you start it up or later down the road.

closed and open loop play a role if you use a o2 sensor

Well it idles like that all the time. But it only bogs down like crap when driving. Do I need to get a new o2 sensor??? I am using the one that came with the motor.

wouldn't hurt to get one. but you can also check it i forget what the voltage should be. also i like to clean the o2 sensor every now and then with carb cleaner.

also the voltage you got for the maf seems way too high it sould only be like 1.5v

I got 1.5V for the TPS, and 12V for the MAF. From what I read I should get 12V on the black wire and about .5-1V on the white signal wire. Can someone confirm this???? Also would the AIV Valve cause this? I can't guarantee but I bet that the boost leak was the reason for crappy driving, I will check that in the A.M but now I still have the idle.
Chris

well if ir runs good but idles bad you could adjust the idle air thingy, or even your timing. but if the timing i right mess with the air thingy

by the way where's fsar?

We tried that with very little change. My friend is bringing a timing light tomorrow so we can check it.

Anyone know how to adjust the TPS???

loosen the two bolts holding it on and move it side to side and when it sounds nice tighten the bolts
