So just recently my van has developed this problem where after roughly ten minutes of driving the check engine and vsa lights turn on amd the car will shake pretty bad when idling while in gear at a stoplight for example, the oil just got changed and also just had the spark plugs replaced, the van has 226,000 miles on it
So if the check engine lights up, what are the codes it sets? Ignore VSC for now, it typically lights if the CEL is lit.
You can get the codes read at most auto parts stores for free. Do that and post the actual codes, not jsut the counter guy says they are. It should look like P1234, in that format so we can try and help.
