searched but need more assistance

its been about a year and half now and its drivin me nuts.. i replaced the IAC and it fixed it for about a week.. then back to the messed up revin idle in park and neutral (its not happening in drive and reverse)

no leaks that i can see
replaced iac
replaced coolant temp sensor

Should i flush and refill my coolant to make sure there is no air bubbles.??
TPS?


Does any place like autozone do diagnostics for free? if not how much?

Idles at 1400 to 2000 when reving.. and when it doesnt rev on its own in drive(sometimes-usually when i first start drving before it gets warmed up completey its at 1200-1500.. i want it down to like 800.. how can i do that???

Starting to bog when i let off the gas sometimes

at stop signs it will want to stall but when i hit the gas its fine?

driving me nut?

btw.. where can i get a good fuel filter? i saw aem for like 110.. but how bout stock or something from pepboys?

 

I use a regular Pur-o-lator fuel filter on my Civic with a B16, and I have no problems with fuel flow. It probably makes around 175HP at the fly with the mods I have.

Start checking your vacuum lines for starters. After that, get a Helms manual and a multimeter and start checking your TPS + other related sensors.

 

Not to sound dumb, But how do i go about checking the TPS? I have a helms manual so ill look in there.. but want some other views as well

and how much did ur fuel filter cost??
