AC problem on series 4

[raycor]

mga bosing, i think may nakaka experience nito sa mga series 3 or 4 owners. ask ko lang sa series 4 ko ex saloon manual tranny, ano po ba dapat gawin o e adjust pag naka on yung aircon tapos mag kinabig kabig mo manubela ay namamatay po yung aircon pero mag oon din uli. then pag nasa 1st or 2nd gear which is slow traffic driving lang, pag nag on yung aircon, biglang kadyot yung oto na parang tinulak yung oto. pero pag mabilis yung takbo ay di na mararamdaman yung kadyot pag nag on yung aircon although maririnig mo yung aircon na nag on by the relay sound. sa 1st and 2nd gear lang po sya kadyot pag nag engage to on yung aircon. parang shift shocks hindi tuloy comfortable mag drive ng low speed. any comments po mga boss, thanks

raycor,

para sa kadyot na problem, try mo linisin or ipalinis yung throttle body, including MAF. Also check for possible air hose leaks.

then para dun sa automatic na nag-tu-turn off ng AC when turning the steering wheel, you'll notice a pressure sensor and connector at the end of PS hose, yung malapit sa right strut tower at windshield wiper motor. Ayun yung responsible dun.

i hope that answers your questions.

sir acupalypse, nalinis ko na kanina yung buong TB pero di ko pa na test drive. i set ko pa idle nya kasi ang taas. may procedure ka ba sir kung pano e adjust ang idle nya after cleaning the TB? pano na po yung plastic screw para sa idle adjustment, parang sasagad na po kaka adjust, i think clockwise pag ibaba yung idle, pano po pag sagad na? yun naman pong sensor sa PS hose, ok lang po bang kalasin yun at walang pressure na sisingaw?

pre,

i assume your engine is ga16dne.

after cleaning TB and idle went high, here's a sample guideline how to reset the base idle:
1. warm up your car, revving the engine intermittently (~2000 - 2500)...be sure not hot enough for the rad/aux fans to turn on
2. turn of your engine
3. disconnect TPS connector
4. start your engine and rev it a few times again for about a minute or 2
5. turn the idle adjust screw until rpm is between 700-750 (not sure about the exact value; AT has different settings from MT)
6. rev the engine a few times again and be sure the idle rpm goes back to where u set it
7. turn off your engine and reconnect TPS connector

that's it...

thank you sir sa pag post ng procedure, ginawa ko na. pano naman po yung timing nya? gusto ko rin sana e adjust kasi mas lumakas sa gas na compare nung di ko pa kinalas yung TB. pansin ko kahit binaba ko na yung base idle, tumataas parin yung idle. pag nirerev ko ng 2x ayun sumisilensyo yung engine, pero pag on ko mga lights, blower, AC, galaw steering, tumataas nanaman at nagiging rough sya. pag enoff na lahat, ayaw bumaba idle hangang e rev mo nanaman uli. kahit pag tumatakbo pansin ko mataas parin idle, kelangan din po ba i adjust yung timing sa distributor? malakas kasi sa gas. wala naman ako timing gun. sabi nila mas accurate daw ang CONSULT. my engine po pala is GA14, ex saloon po manual, thanks
