Engine Misfire after heating up
Hi, I have RX300 99’model. the engine misfire when its heating up and the heat indicator show just a little over half. Already checking coils, already changing plugs. and i even changed the distributor. yet the problem still persists . it is not like misfiring all the time but when i try to over take or climb up, i cannot raise above 50 at all. i had to ease on the accelerator little bit and press it again then ease again then press it again. Can anybody help me with that please?
