I have kind of a strange suggestion but it actually is what was wrong with our Grand Marquis. The Catalitic Convertor (however you spell it) had come apart on the inside. The Convertor was making a horrific vibrating metal noise when given gas and not when idling.......only when you gave it gas and changed the pressure on it. It took two different mechanics to finally figure it out. The convertor was not actually stopped up - it had just come apart on the inside.

Is it when you are driving and push the gas? or when parked and rev up?

things that come to mind; worn valve guides, spun rod bearing, but also could be something that has nothin to do with the engine.

If it is a lifter then change the oil and add Rislone to the oil. It is an additive that has been around 50+ years and works great to free up sticky lifters. Start changing your oil more often will also help.

My 1997 Chevy c1500 5.0L misses very bad with loud poping noise coming from underneath truck. This happens only after I drive for about 30 min. And turn off truck and restart. After I start it back up it...

Test that the temperature sending unit in the water system is working properly. When the engine is cold, the computer puts it in cold start mode. Once warmed the temp sensor tells the computer to stop sending excess fuel to the engine and taking the cold start mode to off position. If the sensor is faulty, it stays in cold start mode and keeps dumping excess fuel into the engine causing your situation. Like your running with the choke on after warm-up.

It may be the pre amp in the radio, happened to me in my 03 sierra, it "sometimes" happens because it gets warm/ hot, pretty soon it will cut out all together.

1997 Chevy 1500 P/U 4x4 small V8. Transmission shifting issue.

you may be confusing the torque converter clutch engagement with o.d. this trans has a problem with the T.C.C. regulator valve wearing out the valve body bore. this will cause the converter clutch to engage only sometimes or not at all. this will set a P1870 code in the control module. when this code is stored in the controller, ( check engine light may or may not be on), it increases the pressure in the transmission causing the 1-2 shift to be harsh. ask a local tranny shop to scan the vehicle ( most will do this for free) if this is the problem they can either fix your valve body (sonnax parts) or replace it with an upgraded valve body. hope this helps

Lifters sound like they are bleeding down. Try changing the oil with a multi viscosity oil. chk oil Pressure. If lifters are over adjusted the lifters can't pump up properly or retain the oil properly

Loud Clatter in my 1992 Taurus

This totally sounds like a Muffler Flange has come Loose. Have someone get in and lightly hit the Gas while you walk around the Car and find out exactly Where the sound is coming from.
