92 accord ex wat did i do wrong?

rmps going up and down only in park..it dont go pass the 3 it stays between the 2 and 3 when it..only do it sumtime...indle at 2........other then it runs fine....check engine comes on sumtimes when going 70mph then stay on......dont come on when frist start the car sum times comes on sum it dont......i just put over 400 in parts... new intakebody,,,new value sencer,new value, new water themostat new waterhousing,sparkplugs...new wires,oil change, oil fitler, air fitler,all new hoses also vacuums and so on....i dont now wat i did wrong....lol IT PASS SMOG BEFOR I DID EVERTHING i just wanted to make it run better.. i say it runs 100% better then it use to...i fix a lot of probs but i cant seem to fix the idle high and rmps going an down in park sum times and the check enginelight coming on sumtimes...

did this before you done all that? if not sounds like tps sensor or you may have vaccume hoses crossed. you said check engine light comes on so if you go to autozone or advanced when light is on take it there and have them plug it in and see what computer sais is wrong with it.

yeah it did all that befor i done everything............i just found out that the control idle they put on was off a 91 honda accord 5spd.......and my car is a 92 honda acoord ex auto.....can that be the reason? and at the top of the intakebody the person i got the car from blocked of the first vacuum? maybe that rhe prob tooo.a friend told that there is a control idle srew that i can lower the rmps if i wanted? is that tru

It is adjustable AND controlled by the computer. There is an idle
control screw somewhere on the throttle body.

If you have fluctuating idle, you most likely have a vacuum leak
somewhere, so try to find this before you adjust anything. Fill up a
squirt bottle with water (others recommend using carb cleaner) and spray
a fine mist around the various parts of the intake system. When you get
a drop in idle speed, you have found the leak.

If this does not work, start pinching the various vacuum hoses until you
see a drop in RPM. If you do find a hose that allows you to drop the
RPM, follow it to look for leaks or faulty valves etc.

Another thread dealt with the same issue on a CRX. The original poster
in that thread found that his fast idle valve was leaking. It is a
thermo-wax valve that allows extra air in while the coolant is cold. His
was leaking air all the time.

If you do need to adjust anything, first get a shop manual as the
process is not completely straight forward. The best manual is the one
from http://www.helminc.com, but if this is the only work you are going
to do on the car the Haynes manual would probably suffice.

There is a stop screw on the throttle body (close to where the gas wire
is) that looks like the idle speed adjustment on carburetors. Do not
touch this screw, as it is factory set and is not used to regulate the
idle.

so today i just adjusted the cable and it seem to idle fine not high.....and rmps dont go up and down (werid)...now..i have a diff prob.....it use to get hot while driving.i fixed it...and now...the temp says it hot when its park...but its in the middle and not over heating when driving.....my fans work...one say on the other comes on when the ac on.stays on when the car is off...i just replaced the thomastat sensor...my only guess is the cooolant temp sensor?....i just bought one havent put it on yet.... when i put gas in the gas tanks 45sec later it click..mybay a persure prob?



thanks for the help you guys....

they want 500 for tps...they only have it for a 90-93accord 2.0 si.........and 94-97 ex f22b1....mines is a 92 accord 2.2ex 4dr autotrans....

and know its also shaking now..(when its in park and when u sittn at a light)....and the checkegine light pop on when on the freeway but not in the moring the car is cold and some times it do..but in the atfernone sumtimes it pops on then stay on..takes like 15-30 mins for it to pop on stay on.but it dont come right on when starting like most cars.......i thhink it have sumthing to do with the coolant temp sensor.....
