high rpm when neutral

[duncan_sheek]

Need your opinions mga bros. rpm increases when I shift to neutral(around 1800 to 2000). When the gear is engaged(1st, 2nd and 3rd), rpm is normal around 1000. What should I check or what should I have it cleaned? Thanks in advance.
Vehicle is EK civic 96 vti

Have it checked. 1800-2000RPM is not normal. Cruising speed ko na yan sa highway eh.

thru my experience ang sasagot ko kasi ganyan ang nangyari sa akin month ago, tumataas more than1500rpm , at kapag malamig ang makina one click start agad but pag bagong patay ang makina ang hirap magstart, then pag tagal tagal umilaw na rin ang check engine light at pag pinatay ang makina at re start nawawala ang CEL at umiilaw pa minsan minsan, pina reading ko ang CEL kay Mel Casaba (FOC), faulty ECT sensor, sa evangelista ako nakakuha cost of surplus sensor 550pesos labor 200pesos,ayon pagkapalit nawala na ang mataas na RPM , mahirap na start kapag mainit ang makina , at wala na rin ang CEL.

up ko lang ulit. driving this morning it happened again. When gear is engaged, normal ang rpm but when I shift to neutral, rpm increases(1500). Halfway thru my driving, I turned off the engine and restart, ayun normal na ng konti.
There must be something that keeps the throttle stuck open. I'm suspecting vacuum leak, bad ECTS, bad throttle body seals or general throttle body problems??? Before I take it to the mechanic I want to know how to explain to them baka galawin nila ang di dapat magalaw. Thanks.

*raine - salamat bro, but I guess medyo iba yata ang case ng sasakyan mo bec mine doesn't experience hard starting and the CEL doesn't light up abnormally.

better have it check sir.

update:
I went to the mechanic and have the throttle body and IACV cleaned. Also adjusted the idling. Its back to normal now. Thanks for the replies.

cleaning the tb and idle up should always be the first step.
