Hello everyone. Hope you all are doing good!
I have recently purchased an unregistered 2006 Vitz (AT – petrol only) from a local dealer here in <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com</st1:place><st1:City w:st="on">Islamabad</st1:City>. Soon after I had it, I got it thoroughly checked (40,000km inspection and maintenance) from Toyota Motors Dealer in Aabpara Market. Resultantly, I got its air filter, oil filter, fuel filter, engine oil, AT oil, sparking plugs, replaced. I also got the throttle-body serviced.

Now the issue is that from the day I purchased it, it is consistently have problems with its acceleration. I mean it is not the typical pick or acceleration issues you would have with 1000cc engines. While I am driving and accelerating suddenly the car stops accelerating, and becomes neutral (the gear doesn’t shift to neutral but the car just wont accelerate) as if the air intake (or exhaust system) is choked or something. I took it to the <st1:City w:st="on"><st1:place w:st="on">Toyota</st1:place></st1:City> dealership again, and they removed the CAT converter. Yet there is no relief, in fact, the problem has worsened. Now, I am having issues with normal pick-up and acceleration as well, in addition to the existing problem.
Kindly suggest as to what could be the reason for this problem. Is it an electronic issue (because the computer the mechanics are using don’t indicate one), or air intake/exhaust problem? Furthermore, which mechanic would you guys suggest?
Your feedback would mean a lot to me.
