2700$oarer

hello, im new to this place obviously.... anyways long story short i probably have one of the cheapest cars on here at a grand total bill of $2700... no performance upgrades... the car was wrecked and i bought it before it went to the junkyard to save... the car has 100,673 miles on it once it was finally up and moving again... its at 101k now... recently the car has been having a stuttering issue under acceleration around 1300+ rpms, feeling like a stumbling in the motor and power loss... recently i decided to romp on it after i started putting premium fuel in it and it made like a bogged acceleration noise... and smelled like gas? my question is.... is it possibly the sparkplugs? the car was sitting for about 5 months.... and ran fine for about alittle under three weeks, no engine light yet.... any help would be great.. thanks!

welcomes to CL. I think one of your ignition coil is bad. Your SC400 has 2 of them, one on the top of the engine by the thermostat housing/upper radiator hose and another one by/top of the A/C compressor. Check those ignition coil first.
