I have a 1989 200tQ with a rough idle but when put under load it almost feels like a boost leak would tested that, pretty sure its good.. recently had a problem with the car missing very bad, had checked the plugs and wires before due to the problem above.. this time pulled the cap on the distributor the rotor was just gone... ya idk must be getting too much voltage probably the wrong coil, but car hasnt always been like this started acting up id say like 2,000 or soo miles after new engine put in. ohhh there is an injector leaking?? was mainly wondering if that could be causing these problems??? anybody with knowledge behind these problems, i obviously need some help thanks

 

Problem fixed...turns out spark plug wires were arching all over the block.. so put new plug wires in and problem went away.. if anybody has the same problem check that at night or in the dark.
