My car was recently acting up with feeling sluggish from a dead stop and having issues accelerating. We thought it was the Throttle Body, which we replaced and no change. Then my car was also throwing codes saying it was the Crankshaft Sensor and multiple cylinder misfire. So my husband changed out the sensor and then changed all 16 spark plugs where 14 of them were fouled out. After he was done, went to test drive and nothing has changed! What else can it be?! Feeling frustrated cause its also resulting in me only getting like 100 miles per a tank, I have literally filled my car up 3 times in the past 3 days.
