88 5.0 making popping noises from exhaust? April 11, 2005, 09:49:14 PM What would cause it to make a popping noise. Seems like it does it when it is at around 1000- and up RPMs. Im not sure what it could be? Also when my friend check the oil, he said it was thin-like and smelled like gas was in the oil, but would that make it to pop pop? Anyone know? Thanks Quote Selected

But without a better description of you problem, you arn't likely to get a lot of help online. The gas in the oil is because of either a over rich condition(possibly MAP sensor or fuel pressure regulator), or maybe a iginition problem(spark plugs, wires, dist cap). Quote Selected
Re: 88 5.0 making popping noises from exhaust? Reply #10 – April 14, 2005, 11:02:01 PM Do you know where I can find a diagnostic tester for a decent price? oh yea, what is the MAP sensor? thanks for the imputs, I appreciate it. oh yea to confirm things, when you run codes where do you plug it into: the EEC or ECU? I believe it is EEC, but some people were telling me ECU, so i just wanted to confirm things. THanks again. Quote Selected

Grab a voltmeter, a test light, or just a little piece of wire, and find the two EEC test plugs.Here they are:. Here's what to do:.QuoteI believe it is EEC, but some people were telling me ECU, Same thing.Quoteoh yea, what is the MAP sensor?Manifold Absolute Pressure sensor. Tells the EEC/ECU/Computer how much vacuum is in the manifold relative to the outside air pressure. It lives on the firewall behind the manifold and various other pipes and hoses.... Quote Selected
