I have a bone stock '94 Integra LS with 217K on it runs smooth and as quiet as a new honda.....anyways i figured it had such high miliage i would get a quart of that "Motor Flush" i let it run in there for 10 minutes then changed the oil as said. immedieatly after the car "chugs/sputters/cuts out" or what ever wheather it sitting still in drive or giving it any throttle......how ever if i'm going and then let off the gas it goes down the tach smooth with no cuts untl i press the gas again. What Could this Be???????

What i tried to do was change the spark plugs ( 1 black tipped and three white tipped came out) and i drove around the block with new plugs YEAH it was smooth idle and no cut outs even under moderate load.......Until i put it in reverse (yes it's an auto) and it starts to cut out again, so i take it around the block again and it cuts out the whole time under throttle again WHAT THE HELL it cuts till about 5500 rpm always ........HELP

How did the wires, distributor cap, rotor button look? Have you changed any of those recently, if not then you may want to do that and see if that helps.

 

a engine that high mileage, has allot of carbon build up and when you do a motor flush you could flushed away some of the carbon build up in the engine when that can help seal up the engine and keep the compression good, check the compression and see what it says, thats what i would do .... a engine that old mite as well leave it just the way it is if it was running good, why fix sumthing that aint broke...?

 

Cap and wires looked fairly new.......ANd like i said i changed the plugs it ran like new around the block went to park it and it started to stutter again.....And did the whole time around the block the second time.

 

do you have a compression tester?

 

No i dont.....But that motor flush could have [freak]ed up the compression really? But why would it have drove around the block perfect right after i changed the plugs???? I was thinking something to do with the fuel system.....

 

Problem Solved...For now.

Well i did the plugs last night at like 3am, and added some Lucas fuel system cleaner as well. Anyways i started it up and went to wal-mart just not (about 16 miles round trip) And it ran SMOOTH and quiet with no stutter the whole time.....[freak] YEAH!
