RPM problem!

[lancer557]

my car is 1995 lancer glxi. The problem is kapag dahan dahan kung inapakan ang gas, kapag umabot na cya ng 1700 rpm magup and down ang rev nya while naman habang lumalakad na cya may konti palya ang makina. Pero kapag mabilis ang apak ko sa gas ay okay lang naman. habang naman dko cya inaapakan ang gas steady lang cya. and kapag lampas naman ang rpm ko 1700 ay ayos na anday ng makina.

anyone experience this kind of problem?

jumping idle can be caused by a malfunctioning servo unit (also known as idle air control valve or bypass air control valve).

since that's a 1995 lancer, i'd put my money on malfunctioning servo since almost all lancers and galants i've heard of have this problem.

have the clutch system checked. baka pressure plate...just had mine replaced...clutch nagslislip from 3k to 4k nung una...akala ko nga normal lang. then the next thing I know, ayaw ng magshift from first gear...

dba kung sira ang servo niya dapat kahit naka idle lang cya gumagalaw ang rpm niya? and why sa around 1700 na rpm dun lang cya nagloloko over or below it ayos lang. i just had my car oil changed last month. Nalinis ang air filter nya, . It started ata nung muntik na ako mauubusan ng gas, iniisip baka yung kinarga gas sakin baka may tubig,or dahil paubos na yung gas yung stock niya sa tank marumi.
