My 2005 Dodge Grand Caravan started to run rough and engine light came on. Took van to AutoZone for diagnostics, but no codes came up. Guy told me it probably justs needs a tuneup so I changed the air filter first. No change in running condition and engine light was still on. Next, I changed the spark plugs and spark plug wires. Now the engine lighjt no longer appears, but it still runs a little rough. Startup and idle are ok, engine does not stall or anything, but hesitates when accelerating. What what be the next thing(s) to look for?
