I have a 2003 Honda CRV AT which is having a acceleration problem. I'll try to be detailed as I can about what happened and I may get some technical things wrong because I am not really into fixing cars.
I bought the car from my brother knowing it over heated before. I got it knowing it was fixed before and if it still fails, I will just buy a new engine and replace it. I thought it would be that simple.
So after using the car for a while, I notice that the engine is losing so much engine oil without any trace of dripping at my garage. I got worried that internally it may screw things up. I also notice a bit of mud like stuff in the radiator cap. So I went to a mechanic, told him the problem and insisted that I will just get a surplus engine and replace it and so I bought an engine, he put it in but to our dismay we got a bad engine so as per my mechanics advice we just went and brought it back and have our cash refunded. Also, there was a check engine light. The seller said, the mechanic did not adjust (something in) the transmission thats why it making that weird noise. But we still returned it back. The mechanic said he can fix the engine and I trusted him because the way he said it was he was so sure he can fix it.
What he did was went to a machine shop, made the cylinder wider, and inserted a sleeve. Mechanic's reason is that one of the cylinder went oblong because the previous mechanic used an oversized piston ring and just cut it short to fit. He showed that to me. Also, the top of cylinder block (not sure of the term here) was machine shoped so it will be straight flat.
He asked us to buy new engine oil (top 1 brand full synthetic, forgot the spec), new ATF (Top 1 DM-3) and coolant. After all was done, there was still a check engine light, he said he doesnt have a diagnosing tool so we went to his friend mechanic to have it checked. So we went, but along the way, we notice that the car sometimes loses power while running. What I mean by that is that when we are running around 30-50kmh the engine will just rev. Its like stepping on gas pedal in neutral. Also he had problems going to reverse gear. He asked his helper if he put in all the ATF and the helper said yes. Sometimes we had to stop, turn off the engine and start again to make it work again. D also blinks. We checked the ATF and saw that its almost empty. We stopped by a shell gas station and filled it with Shell ATF, again I am not sure what that is (I know I am being stupid here by just trusting the mechanic). And so we went to the mechanics friend who has a diagnosing tool. I am not sure but I think the check engine said it was valve timing problem,again not sure just trusting the mechanic. He went back to his shop and tried to fix it. I called the next day and he said the reverse problem was just a wiring problem and it was fixed. However, he cant figure out the problem with the transmission so he went to another known guy here at our place to have it fixed.
So he brought the car to this shop, this guy has all the tools, lifts etc and is well known as a good mechanic at our city. During this time I started researching online. I called them and asked things I have no idea before. I asked if they checked the fuel injectors, MAF Sensors, spark plugs, the solenoid in the trasmission? Said all was good. after a few days, they said its fixed. I asked if they did something in the transmission, they said no. he said the timing was wrong. So I test drive it for about 3kms and all was good. During this time I am feeling happy. However he said that battery is dead which I am already expecting. True enough the batter was dead the following day so I borrowed a battery to drive the car.
..to be continued.
