    I have a misfire anywhere from 1500-3000rpm if I’m slightly on the throttle. If I lay into it a little more instead of barely pressing the gas it won’t misfire It’s a very wierd misfire as if it just skips one fire or the fuel is cut for .1 second then is perfectly fine and won’t happen unless...

    I have two key issues with my 2001 Lexus IS300. I managed to fix one, however after countless repairs I can't fix the second. The first issue is that the car wouldn't respond to the acceleration pedal being pressed down. I managed to fix this issue by replacing the the throttle body. The...

    My is300 2002 makes random misfires more frequently at cylinder 2 but also 1 2 3 4 but rarely. Idle run great I looked a little at everything related to the ignition but I found nothing. Any idea before compression test? 250 000 run great but check engine light on. Any idea what it could be?

    I’ve been having misfire issues for a while now. I thought it was because of a vacuum leak so I replaced all the cracked hoses but the misfire continued. One of the hoses I replaced is pretty kinked but still has air flow, I attached a photo of it (the one that bends downwards in photo) does...

    Hey people, it seems I am in need of some assistance...

Happens mostly at idle and little acceleration but...

    Okay, so here's my tale of sorrow... when i first got my 5 speed IS, i thought it was running fine. Yet, somehow there was popping on idle. I didn't think much of it.

    Valves, Lifters, Cams, Hoses, Radiators, Pumps, Headers, Intakes.. etc etc. All have been replaced, Engine is Oil free and could cook a egg on it. New plug wires, New Plugs, New Vacuum hoses, yada yada. As I said in a post a couple months ago, car has had "dodgy" if that term should even be used...

    I have a 2002 Lexus is300 that’s been acting up recently. Car would idle really rough on idle occasionally and would lack power. I took it to get scanned and got codes for random misfires in all 6 cylinders and also got code P1349. I first did a tune up changing all spark plugs and oil, filter...

    Heading to work the other morning I felt the car start running a little rough. At first I thought it might have just been a hiccup, after all it was cold and the car's got ~250k on the clock. Paid closer attention and felt it definitely missing, so I turned around and limped back home. The car...
