I looked at the previous postings a little, and I realize it is "spark
knocks" that I have. They get worse when the weather is hot. On a hot
weather and engine hot, I press the gas, the car practically can't go
uphill, just knocks almost no power, but still runs on. It only
happens under load, driving. For example if engine is running parked
and I press gas, it goes to 3-4K rpm no problem (as if everything ok)
with good engine sound.
I run the KOER test today, I got 538, I guess it is something like
"not enough RPM", don't know if related to spark knock problem.
To Scott's question, engine turns off immediately when I turn key off.
No weird behaviour on that. Idling is good. Cold or hot, always starts
I have Hayne's book, it says I have MAP sensor (doesn't mention about
MAF). Are they the same thing? I guess I know where it is, but I will
take its picture and post it to be sure. How do I clean it?
I located both O2 sensors, plan to change them first.
I checked the hoses, they look ok. But there are many hoses, and some
of them I know have hot water in it. Should I check only the vacuum
hoses? How do I know which hoses are those?
Since car seemed to heat up a little too much, we changed the
thermostat recently. Where is the water (coolant) temperature sensor?
Fuel filter is 8 months old, it should be ok I believe.
Thanks in advance
