If the check engine light is on have the codes read and post them here. FYI - The numbers on the tachometer are thousands.

check your coolant to see if it is full. check when cold for safety. temps are kinda high.. unless u ideled for 20+minutes. look at coolant. should be orange . also.. like the above have diagnostic codes read from your computer at aaa or pepboys or o'reily's . good luck.
