Hey Scotty, love your show.
So, I bought a tiny toyota IQ city car, 160kkm(circa 100 000miles) manual transmission, 1.0liter engine(I know, its pathetic, here in northern euurope we like driving small cars..)
I started noticing the car getting very lazy, especially when cold. You give it just some gas and everything seems fine, the motor runs real smooth. Try to go up a litlle hill and give it some revs, and the motor doesnt react, cant accelerate, and struggles. When it warms up it gets better, but is still even lazier than a 1liter engine should be. I took it to the shop, they changed spark plugs and cleaned the egr valve, did help a little. No error codes. Air filter is fresh. The damn thing doesnt have a recognizable MAF sensor to be cleaned.
Then the check engine light came on, the shop changed the oxygen sensors and that did help even more, but the problem remains. Fuel consumption is also higher (some 33mpg on highway) than expected for such a small car. Been to a couple shops, they cant figure out whats wrong, Ill be taking it to the certified toyota dealer next. If they cant help then I dont know whatll I do.
Any thoughts?
Did anyone inspect the catalytic converter?
@inthedetails
they did the anti-pollution testing, and the oxygen sensor data should be ok (as I was told, but didnt see with my own eyes), so I figured that would be cleared. The same shop does compulsory anti-pollution inspections, so I figured they should know their stuff
Besides, the car runs fine when warm and stable revolutions(say 60mph, 4000revs), its the acceleration that is the problem. If the kat was clogged, wouldnt that be affecting the running all the time?
