weird off idle stumble/misfire

[maureen]

did you find any solution yet
mine is doing pretty much the same thing
when the weather is hot
rpm jumps from 2 to 3 up and down
but the speed stays at 60mph

does it happen when taking hard left or right turns ?

while cruising does rpm suddenly drop then pick up ?

i had a problem similar to yours back then.

i would be driving at like 70-80 and rpm would drop down to 2k and jump back up with the slightest jerk ever.

on canyon runs i'd be at wot thru a corner and same thing would happen.

one time it got so bad to the point where if i would hit a dip my engine would just die.

i replaced fuel filter, coil pack, spark plugs and wires, also put my timing back to spec cuz i guess previous owner messed with it and problem solved lol. i had a 1.6

I just had the same problem on my car, for me it was a plug wire that was shot. The one on my number 3 cylinder had burned/rusted through right where it connected to the plug, I had ordered some ngk blue wires what will be here in the next week but for now i just got a cheap set to hold me over.
