Misfire / Mahina Hatak

[Jeh]

Hi sirs! I would like to seek for your advise and inputs regarding the problem of my Ford lynx ghia 1.6 (gen 1) manual transmission. Trying to save as much as possible from buying parts and testing it and also the labor, since the culprit could not be identified easily.

Symptom:
Misfire
The misfire (palya) can be felt when the car is running since sobra po yung pagjejerk ng sasakyan.
Dinig din po to since nakafreeflow muffler yung kotse, may times na napuputol yung tunog nya.
The car runs smoothly pag malamig pa makina, but when it gets hot, nagsstart na sya magmisfire.
No erratic idling and the car never stalled. Its almost 2 months na ganito po sakit ng kotse ko.

History:
The engine bay was infested by rats. Rat droppings were present in the engine specifically in the coils. These caused the coils to warped and eventually failed resulting to misfires. At first, since di pa nakabili ng parts, pinalinis ko lang spark plugs at nilinis din ng mechanic yung "servo". Pero ganun padin, but these time parang tumigas tunog makina and i suspected baka di lang nakuha tamang idle. A week later pinalitan ko na ignition coil, coil packs and spark plugs, cleaned maf sensor and crankshaft sensor but to no avail. Same symptoms padin po ang nagmamanifest.

Planning to take it to CASA for scanning, unfortunately, wala na daw OBD scan mga ford CASAs. Kaya, if you can also recommend po shops na nagreread ng OBD. My area is Evangelista St, Makati.

Any inputs or advise will be appreciated. Thanks!

how many ignition coils does the engine have? does it have wasted spark system (one coil per two cylinders) or does it have COP (coil on plug- one ignition coil per cylinder)? check your primary wires for broken circuits or if equipped, check your secondary wires (high voltage spark plug wires)

Thanks sir. The car has two coil packs only and has its own ignition cable attached to it. Lahat po to brand new na.

If I may add mga sir. Yung misfire at palya po lumalala if the aircon is on.

one cylinder misfiring ay 75% lang ang engine power mo plus dagdag mo pa ang load ng ac kaya hirap na talaga ang engine mo. also running an engine with misfire will ruin your catalytic converter. we have carman scan lite in the shop if you're interested vito cruz extn lang

I think we have the same problem. Parang sinisinok yung car is how I describe it. Civic yung car.

Pag malamig pa hindi sinisinok, pag taas ng temp needle lumalabas na yung sinok. Kahit idling maririnig na parang nagiiskip yung idle. Yes, mas ramdam pag naka-on ang aircon dahil siguro mas nabawasan ang hatak pag sininok.

Hindi rin erratic ang idling, hindi gumagalaw ang tachometer needle. Wala rin CEL.

About sa mahina hatak, I already had it checked sa casa nag-adjust sila ng valve clearance. Nabawasan yung sinok and I think lumakas hatak pero not sure though mas naging responsive. Binalik ko ulit sa kasa and mga basic troubleshooting muna ang ginawa para hindi magpalit ng parts na hindi naman pala ang culprit. May mga nilinisan sila sa distributor and ibang parts hindi ko na maalala yung ginawa. Mas kumonti ulit ang sinok pero paminsan minsan meron pa rin.

Ang hinala ko is high tension wire pero since pag uminit lang lumalabas yung sinok would this mean na something mechanical ang problem?

^^^baka kelangan mo nang palinis yung fuel injection system mo.

Had that during autotechnicas days for freem

have you had the pcm scanned? for lack of information about your car, what month and year was it produced or what engine family does it belong?
