This could be a multitude of things but my first suggestion would be to change the spark plugs. They are cheap and can be bought at any auto parts store.

iCON, you mean IKON< right?

HOT and cold engine,
Is hot idle speed RPM right near 800 and steady,not racing fast?

power loss, is the CEL lamp glowing running, yes,scan it.
post engine type exactly. one of these?
1.3 L I4 (petrol)
1.6 L I4 (petrol)
1.4 L I4 (diesel)
1.8 L I4 (diesel)

so its the first 2, as you said, coil, so its a GAS engine.
power loss, do the 60k tuneup
clean the MAF, sensor. if it has one. ask how. first.
does engine power return , at wide open throttle, held? up hill?
yes/no
if no, weak maf, air leaks or low fuel presssure
if power loss is only brief, then bad TPS.
my guess this engine, is MAP based, no MAF,
if so, then clean the nipple on the MAP sensors.
make sure its not clogged .
If the map works ,any air leaks cause fast idle. and FULL POWER>
so id bet the power loss is from low fuel pressures.
that is why i ask for WOT power up a hill, hot, got that.
if just tip-in power loss (recovers) that is a bad TPS.
the do wear out. easy, at 100k.

there are 2 EFI systems, which one yours has im clueless but can fix both , easy. (maf or map based) aka. air /speed density systems.

Chugging and wont accelerate


My first guess would be low fuel pressure or a faulty throttle position sensor. The faulty sensor should turn the check engine light on.
I would check those things first.

1997 Oldsmobile Achieva - check engine light is on and car is running sluggishly...brand new motor installed 6 weeks ago.


What speed are you going when it chugs?
It could be as simple as a bad spark plug or a spark plug wire/boot grounding out.
When spark plug boots get old, the rubber cracks and lets voltage arc out the side and to the engine instead of through the plug.
This will be most noticeable when trying to maintain a speed of over 40 mph, or under mild acceleration.
The reason for being noticeable at this speed/acceleration level is that the transmission torque converter will be locked, transferring the vibration from any engine miss straight through to the wheels.

Was driving down son's dirt road driveway returning home at low speed in 2nd gear in my 1997 sunfire when it suddenly started running rough with no power. it will start right up and idle is rough but...


Sure sounds like a typical case of dirty/contaminated fuel....or a broken vacumn supply hose around the intake manifold area, in neutral let it idl;e and look and listen for a hissing sound, or a broken black rubber hose.
Also have the computer scanned for any possible codes.
Another thing to look at is the catalyctic converter, put a vac. gauge on the engine and see if the vac drops to almost zero...indicating a plugged cat.

P1211 DTC


Loss of power, usually after a hard acceleration; Rough idle; Check engine light comes on, DTC P1211:
Intermittent high pressure oil leakage.
This condition usually occurs when the vehicle is cold and the oil is thick. When performing a hard acceleration, the truck suddenly looses power, the check engine light comes on, and once returning to idle the engine runs rough and won't accelerate. Cycling the key may correct the concern, clearing the code from the PCM will correct it temporarily. If you can monitor data stream, at idle the ICP pressure normally is 400-700 PSI and the IPR duty cycle is 9-14%; at cruise, ICP is 700-1200 pSI and IPR is 15-20%; under normal acceleration, ICP is 1200-2000 PSI and IPR is 20-30%; and under WOT accel, the ICP is up to 3600 PSI and the IPR is 35% or higher. When the above symptom occurs, typically the idle ICP reading will be normal, but the IPR duty cycle will be high--over 20% and up to the max 50%. A "blow-by" condition has occured somewhere in the HP oil circuit. If you can get the problem to re-occur with some frequency, the most probable cause is worn or deteriorated injector or IPR o-rings. If the problem is intermittent, it could be a sticking IPR valve. Replace the injector o-rings with the latest-level kits--F8TZ-9229-AA. When replacing the IPR, make sure you get the correct part for the build date/serial number of your engine.
