Ford Lynx SOS: erratic idle tapos ayaw na magstart

Car:
Lynx 1.6 AT Ghia
2000

Problem: Erratic Idle and now ayaw na magstart

A little background. Months before, I experienced low idle that almost made the engine stop.
Until around April, erratic tapos namamatay na talaga sya, lalo pag mainit ang panahon. Pero
nag-i-start naman ulit, erratic idle nga lang. So suspect is IACV.

So end of April, I open the hose going to the throttle body and sprayed carb cleaner,
madumi na nga din ang TB. After cleaning, unstable ang andar and then nawala na
ang erratic idle - tumino na sya - pero di na masyado nagagamit at bakasyon ang
mga bata.

Pero today, ginamit ko ulit papunta office sa The Fort, after 20 minutes of driving,
nagerratic pataas (4k rpm) at pababa (0.5 rpm) at namatay ang makina.
Start ulit, drive a few meters, super erratic at namatay na ang makina ulit.

Ayaw na magstart, malakas ang redondo ng starter (bago ang battery, April lang din)
pero di na pumipitik ang rpm pataas - nasa zero lang sya. kahit after 30 minutes at
lumamig na ang makina, ayaw pa din.

Towed. Hanggang ngayon ayaw pa din magstart, malakas pa din ang baterya.

Palitan ang IACV? Suspect din is the cam pos sensor. At yung crankshaft sensor.

saan located ang crankshaft sensor? :)
Pahiram please ng OBD Scanner!

Sounds a lot like cam position sensor or ignition coil. Crank doesn't often go out.

is this car equipped with a mazda 1.6 timing belt driven camshaft engine?

Try cleaning the IACV and MAF sensor (pati socket nito kun maluwag at dapat snug fit)

Hth

same problem pinsan ko... pina-palitan ng camshaft sensor sa ford libis ayos na.

Sir, dapat talaga gamitan ng scanner yan para my tamang reference at matukoy ang tamang sira ng sensor mo, para pagnagpalit ka ng sensor sigurado. My OBD 2 ako para malaman ang sira mo ng sensor ng engine mo. Kahit lang dyn sa bahay mo pwede nating idiagnose yan. Kasi ung mga ibang ford lynx na nagpapadiagnose sakin kung ano ano ang pinapalitan ng mekaniko hindi naman pala yun ang sira kaya napapagastos ang may-ari. Ang tamang procedure dyan ang technician mo ay my dalang scanner para sigurado na magawa ng maaus. If you have further questions you can call me 09287618155/7944181.

An OBD2 scanner won't work on the Ford Lynx, since the ECU is only OBDI. A universal OBDII scanner plug will NOT fit the Lynx's diagnostic port. You need the special Ford-only diagnostic socket and an OBDI-compatible scanner. There are a number of shops (Speedlab is one... I think SMT is another) which have this, but I think this point needs to be clarified, otherwise if the thread starter or any other Lynx owners reads the above and seeks to have their car connected to a standard OBDII scanner, they will be sorely disappointed.

BUT... from my experience and other owners, the symptoms are 99% either the cam-position sensor or ignition coils. Most likely cam-position sensor since this is the most common sensor failure on the Lynx.

+1 on the cam sensor sir niky. We have the same model lynx and kapapalit lang namin ng cam sensor couple of months ago. Same symptoms you stated. Medyo mahirap maghanap specially here sa batangas ng cam sensor. Sa casa 8k with a month or two waiting time.

Best to go Banawe. MazFord carries it for 3.5-4k only. :grin:
