My Ford Lynx GHIA 03 is leaking gas to the exhaust

[jtfunky]

I had it diagnosed sa casa ang sinabi loose compression. Hindi ako naniwala kaagad so dinala ko sa talyer d2 samin. He said ung isang injector nka open lng kya malakas ang buga ng gas. Pinalitan nmin ung injector pero same problem pa din. I read somewhere na ECU daw ang problem, i just dont know kung ano gagawin sa ECU... Papalitan ba or repair? Or narereset ba ito. Can anyone help me out... Salamat mga bro.

I read somewhere na sa ECU daw problem.

[blacksun25]

had the same problem with my car (sentra) which is caused by a faulty ECU. it was fixed by replacing the ECU.

umiilaw ba yung check engine light mo? you can try resetting it by removing the negative battery terminal for several minutes. hth.

[jtfunky]

Hindi umiilaw ung check engine. How much kung palitan ung ECU? Hindi ba un na rerepair? Madalas ko kc disconnect ang battery para i reset ung alarm. Mukhang napa sama ata un. Amoy gas ung oil ko dahil dun sa isang injector na hindi na co-close, parang naka bukas na gripo sya.

Bring your car to a repair shop equipped with proper scan tool to eliminate guessing what is the problem/ trial and error method of troubleshooting. Most backyard mechanics suggest you replace this and that but still the trouble persists.

I did bring it to ford Q.Ave, and suggested to overhaul the engine because of loose compression (so much for the proper scan tool), i had paid 4k for that misdiagnosis. Two mechanic from different shops disagreed on ford's diagnosis. Its an ECU problem and it will be solve by repairing or replacing it. Its really better sometimes to get another opinion, 150-200 thousand is ford's q. qve estimate. Its almost the same value of the car, its crazy right? We already spotted the problem and I'm now trying to find a shop that can repair its ECU.

Meron pala nag rerepair ng ECU sa banawe. He knew my problem ng describe ko ang nangyari. Ford q.ave wanted to overhaul my engine and didnt bother to look into my computer. Imagine guys, wla daw cla devise na pan diagnose ng ECU ng Lynx. Meron lng daw cla Expedition at Ranger, analog testing lng daw gawa nila. No wonder hindi nila nakita ung problema at tumingin kagad cla sa naging effect ng naunang problem. Hindi din cguro masyado reliable mga casa it really helps to get a 2nd opinion. Imagine kung naniwala ako kagad, 150-200k later, andun pa din ang problem kc hindi nmn nila nakita ung sira sa computer... Hay naku...

[jtfunky]

OK na Lynx ko.... I will never ever bring my car to ford q. ave or sa kht anong casa na ford. Walang loose compression or kht anong problem ang engine (na sinasabi ng ford q.ave, ung comp box lng, ni repair sa banawe, ayun good as new. Imagine kung pinababa ko makina, how much would that cost. Lesson learned here guys. Ung speedlab... isa pa yan!

What happened at Speedlab?

And are you sure that the engine really isn't low compression? Did they give you the results of the compression test? Because if they carried out the test, and Speedlab carried out the test, and both testers showed low numbers, I'd be worried.

I've had my compression checked by the casa, myself... and the numbers on the machine don't lie. They can be a little low if your oil is really bad, but if they're low enough that the casa tells you you need an overhaul, that means your engine is below spec (usually the numbers will be below 160 psi).

Ford Q. Ave didn't show any results, they just said loose compression. They didn't even bother to check why gas is leaking, i did the test myself with my mechanic. My car is back to normal now, no sign of loose compression or any engine trouble. Speedlab is a different matter, i promised myself never to go back to that place and ford q.ave.

I'm asking because typically, when you're given a low compression diagnosis, they include a computerized printout showing the psi readings of your cylinders. At least, that's what happened when I asked for the compression test from Ford Alabang.

As for Speedlab, I know the managers, and I think they would like to know what the problem was, so that they can correct the situation so that it won't happen again to another customer.

I did asks for the results at ford pero wla nmn cla pinakita, they just said un ang findings nila. People at Speedlab are rude!

I read somewhere na sa ECU daw problem.

what were the initial signs? nangangamoy gas ba pag start ng auto? i think i have the same problem with my RS, but usually i only smell it pag cold start in the morning, rest of the day ok na. i also noticed na lumakas gas consumption ko. my ride only has 20,000 kms on it so i doubt na loose compression yun. pa share naman contact details nung ECU repair man mo sa Banawe, pa check ko din yung akin.

[scharnhorst]

another stealership case!

ingat rin kayo sa ford commonwealth. ginto ang mga parts doon

It's very rarely that it's the ECU that's the cause. In fact, with a busted ECU, a car usually won't run at all. Which is why I'm struggling to understand this case... because it makes no sense.

Right now, your car smells like gas in the morning because the weather is very cold. Add to that the fact that we are experiencing our first bout of really cold weather with the new E10 blended gasolines... which collect water in the tank at night, and your engine really won't run well until it's warm.

And the RS hates cold weather... from experience...

Your fuel economy looks bad, too, because when the weather is cold, the fuel rail return closes, so more and more fuel is pumped into the rail and the tank level goes down. Once the rail warms up, the fuel goes back into the tank.

[celtico1]

actually it smelled like gas even during the warm months, but i can believe that the E10 blend probably has someting to do with it rather than the weather.
i used to make 8 km per liter, but now i'm down to 5-6 km per liter. so parang the case of the injector not closing properly applies to my situation, same with your assumption with the fuel rail thingy i guess.

Amoy fuel at lumalabas sa exhaust... Dinala ko sa banawe ung ecu ko at nagawa nila... Ok na ung lynx ko ngaun. Balik sa dati fuel consumption ko at pati hatak. wla ung amoy fuel at leak sa exhaust.

Hi Sir jtfunky, pwede nyo po bang share kung saan kayo nagpagawa sa banawe? I have a different problem but basically i think its also electornic issue. I have a 02 model lynx gen 2 na po. help po please. thanks!

[lynksys]

mga sir warning lang din ,wag kayo mag papagawa sa cruven angeles walang mekaniko dun puro mason, mamasuhin un pang ilalim nyo at sisinsilin , and hindi pulido gumawa, wala pa warranty ang labor....
