idle problem

[nissans13240sx]

alright i asked before but didnt get to many responses... i have a redtop SR when i start it up it runs and idles great... then when it revs up and goes back to idle it just wants to bog out and then it does. any suggestions

check ur iacv, tps and timing

the fact that its running great i dont think its your timing nor tps. I am thinking a dirty iacv. to clean it take the idle screw out and spray carb cleaner in there and if you have an air compressor blow air in there. see if this helps. also check for code 22 on your ecu if you get this code its your iacv. let us know

how do i read the trouble codes, i only see one red led in the ecu when i turn the key on it flashes and just keeps flashing. i turn the screw all the way to the right im guessing thats self diagnoss like on the KA's computer. not really sure how to read just one led. also where is the idle screw at i didnt look to hard but i didnt see it around the TB ne where. thanks for the help so far

to check for codes...

turn key on...turn screw fully clockwise and hold for atleast 2 seconds....then turn it back fully counterclockwise and you will see a series of flashes..

for example....it will flash once (followed by a very short pause) flash again (followed by another very short pause) and then flash again (followed by a longer pause than the previous ones). after this pause it will flash once (then very quickly after)flash again which would be twice (very quickly after this one) three (very quickly after this one) fourth...this is a code 34. which would be knock sensor.

The idle screw is located on the iacv. that is the screw between the 3rd and 4th runner on your intake manifold. pull it out and clean with carb cleaner and air hose if you have it.

alright man ur the best. checked the codes 22 came up so i did what u said and carb and choke cleaned it and sprayed it off with air hose. it idles great now. thanks alot for ur help

cool man glad i could help. you dont even know how lucky you are that cleaning it solved the problem..did you look at how hard that would have been to replace that whole thing...I am having the same problem right now with my iacv but cleaning it didnt help. i had to pay 230 dollars for a brand new one and gaskets ..im going to be pulling off the manifold and putting it on tomorrow. but congrats to ya man
