Hi Guys Just wanted to let you know that im new on the club, also i just bought an IS200 about 2 week ago with 370K here in Spain, the car is in mint condition However the owner when sold it to me let me know that the engine felt sluggish when hot after he have it parked for about 6 months i did a full service except timing belt seems fine to me still but new plugs, oil, cleaned the throttle body by taking it of the car and cleaning it deeply, we don't have a maf only a temp sensor and a map which i also cleaned, checked for bacuum leaks and nothing and after driving it it has improved a little bit but still if you floor it when hot you notice some hesitation and vibration like if it had a misfire but no code, also the owner told me about replacing the cats bc he thought they were bad so i took the manifold out, cut the precat and took them out, the 1 one for cyl 1 to 3 was missing like a 1/3rd of the core and the second one was intact but took it out also, putted the bacuum on the side were the y pipe connect to see if any of the remains of the cat was loose in there but nothing came out, now the car sound even better and has a bit more of power but still hesitates when hot when floored between 2k and 3.5k like a misfire but no codes what so ever just the normal catalityc below threshole bank 1 but there are no precat on either side just the main one so i don't have any idea, however i haven unplugged the battery for the famous reset of the ECU that i see everywhere so what should i do? and the car idles perfectly just that hesitation when hot if i floor it before it gets to temp it drives perfectly.
