Starts and runs smooth, throttle up. runs rough and it puffs white smoke. Pulled all plugs, no water, doubt it is a head gasket. Could not get timing to set, way high before smooth idle. Replace timing chain, not get timing set to 10 btc, and runs rough. No check engine light, at a loss, no clue, and suggestions?
White smoke is antifreeze try checking the compression

only smokes on a random occassion, no set pattern. most often when you decellerate, and then for just a second or two. its not pure white, its more along the lines of a grey and sometimes a bluish tint. I have warmed it up and removed the radiator cap and the fluid does not spew or raise up and down as if being sucked out and air forced in. If I am going to do the heads, the engine is coming out or removing the hood and fenders. I am pretty handy with anything automotive, but these computers are a royal pain. When I bought this truck the guy had a jumper wire in the OBDII connector. I reset the computer by disconnecting the battery for a day, and it does not run as bad. Could all of this be because he ran it with the jumper wire in it and blew the computer?
I have the same problem and it nomoraly stops with in a few sec of start up. I could be a leaking fuel injector after shut down the fuel injector will fill the engaine and make it run rich on start up. Check oil fill cap if there is sludge on the bottom of cap then the oil and anitfreze is mixing could be head gasket leaking
at idle the 2.0 1998 plymouth neon seems to have a engine miss.as soon as you give it any throttle the engine smooths out and runs fine.what could be the problem
engine also runs rough and quits when idled for long time.
idles rough when starting and blows smoke from the exaust then smooths out and runs fine
