89 lariat 4x4
this truck is in immaculate condition inside and out...no wrecks,dents,and the interior is perfect...the problems with the truck are(see if there is a connection here) it has a broken exhaust manifold(drivers side down the middle)..the number 8 spark plug was absolutely caked with black crap,all the rest were fine...the motor appears to be running on all 8 but does have a rough idle etc...and of course an exhaust leak...also when I drive it I notice from time to time a repeating check engine light that blinks twice then once...I paid a thousand dollars for the truck and feel I did ok but these other little problems concern me...somebody out there please educate me...I am a pro mustang man but know little about these f series trucks...thx
