I am stumped up to this point. The car just out of the blue sometimes after some harder runs will start popping like crazy out the exhaust. This is not the popping under decel that is common, this is during WOT. It seemed to start right after the macs were put on... Bad plugs? THey are bosch platinums

my car did that when it was very rich...would even do it while doing a burn out

Mine did that at the track once. As it turned out a piece of aluminum flashing came off of the head and was slammed between the valve and the valve seat. This was allowing the backfire to come from the intake. It also bent the valve. (I had to correct mine came from the intake but the same thing can happen on the exhaust side.)

I had a similar problem after I put my SLP lt's on. I found a plug wire was loose.

How bad is it popping?

I am having the same problem. At WOT it just pops consecutively. I tried letting off a little and get back on it and it still does it. What's the deal.

after putting the wire back correctly, did it fix the problem?

The popping it like gunshots. It will do it consecutively like 5-6 times till I let off. Then it will do it againg if I get back on it. It will happen like once a night but it freaks the crap outta me. Clogged injector? Cracked plug?

Usually, pop through exhaust is rich and pop through the intake is lean. There are many other factors that can come into play also. Have you a-tapped?? Headers will usually richen it up, combined with some border line plugs coulod break up under load....just a thought.

Mine would do that it, and it was my crank sensor. I rewired the CKP from the sensor to the pcm.
