I hav a 89 Mustang, it has 140k miles, the engine shakes and the chck engine light goes on, wat's wrong?

Question:
I just had the fuel injectors cleaned, the spark plugs are new and at idle the rpm is at 900 and the check engine light stays steady, the only problem I see is that the second spark plug is a slight darker than the rest (second cylinder), but wat do u guys think is wrong? Thank you.

try checking under your distributor cap to see if maybe there is a line that is called a track between any two if the connectors causing spark to jump to two of the cyc at one time .or even plugged up converter, or timing

Will a oil presure switch cause no oil presure and the car to cut off after a few seconds, or oil pump issues?

Bad Motor Mounts could cause the shaking, also you need to have autozone pull a reading from the check engine signal to see what's causing that.
