Got it fairly cheap at mudah, but of course lah... the rust is not that bad, i've seen worst. Will be sending for body works soon thanks to bro mizhans guide.Anyways, i got a small problem with the engine, now lets see if all of us can put our heads together and solve this;The Symptoms No 1;a) During cold start the engine revs all the way to 3000 RPM and screams her heart outb) When i on the aircond, the RPM drops to about 1000c) When im driving around, if i stop at a trafic light and engage the 'P' gear (without aircond), the engine revs up to 3000 RPMNow what may the problem be? i suspect its the idle control valve, or leaking at vacuum hose, or injectors are clogged. Any specific ideas anyONE? <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />The Symptom No 2a) This is a very very minor issue, the aircond blower controller wont work at No 1,2,3 but will only work at No 4. And darnnnn its irritatingb) Went to aircond shop next to the place i got my tires fixed, and he said the priginal control switch tak boleh carik, and want to propose a new switch near the head lamp switch...no way!i suspect it might be one of the relays, but not very sure.... what do you guys think?Thanks guys!</p></blockquote><p></p>
