Random misfire at WOT...
Random misfire at WOT... Over the past few weeks, my car has started to have a pretty bad miss at WOT. It started as just a slight miss the instant you hammered on it, but now if I get on it the engine will continue to pull but miss and shutter pretty bad. I can cruise around all day with no issues until hard acceleration. With the cam, its hard to say if it idles any worse than normal, but it does take two or three tries to crank which it has never done before this issue started. The plug and wires have less than 10k on them so I doubt they are the issue. I've had no codes thrown and I don't have a scan tool so any ideas where to start? Thanks guys.
Hey I had the same thing happen to me when I changed out my headers, turned out there was a small crack in one of my spark plugs, but I would double check the plugs, could have the same issue as me, sorry I am a newb this is the only advice for this problem I can give.... Hope it helps..
It was actually more like the car was shutting off than a miss. Its hard to explaing but for a split second it would shut down and then pick right back up and it kept repeating the process. I unplugged the maf and now it doesn't do it. Is it just a bad maf?
