[QUOTE="deadpool1, post: 440552, member: 21229"] no engine told yes on /MT box if you shift to neutral first. using left foot clutch, does it stall>? if yes engine cased EFI. or fueling all bad, or spark failing got new spark plugs/cap rotor , under 60k miles? the post is not clear at all for sure the 1300 RPm deal is way to vague now my wild wild guess. (on the words I do not understand fully) I guess you meant the EFI has[B] gross idle controlling errors[/B], while only driving. or even shifting to neutral if fails moving 1 N, 2<N 3<N 4 >N shift to N as if it was a gear and report what IDLE RPM is there, at N [B]800 is the answe[/B]r, if not IAC is failing. (assumes A/C is off, nor Defrost mode set) AC dead. AC clutch disengaged. AC on is 1000rpm. is CEL lamp glowing key on, then turns off engine running. In center of cluster see CEL lamp (check engine lamp) if not ever on the lamp is bad. #$74 lamp burned out. a 50cent bulb. Mine are now LED. if CEL on then off running that is good (keyon then running off) if cEL on and ON running that means PCM has DTC error codes to report, 11 to 54,learn to read flash codes. DTCs they are called. key on 3 times fast in 3 seconds max and see DTC errors blink out that lamp. IAC fails for these reasons (and more) IAC is clogged with gunk clean it. (on rear right side of [B]TB [/B]throttle body) TPS failing so bad the PCM can not discover throttle is at idle or TV plate or cable is jamming. ([B]TV [/B]is bottom center of TB) vacuum leaks any hose or causes . here. leaks cause HIGH illegal RPM and is dangerous to teens and some GF/wifes (tell them to key off and get a tow) or engine major problems, compression dead on 1 or more cylinders, no engine told so I guess. high RPm FAILS was cured later with TBw TECHNOLOGY, IF FAILS ?CAR GOES 20MPH MAX OR DIES. (Depends on how bad ) THROTTLE BY WIRE. [/QUOTE]
