What is causeing my Raider mark to multi firer

1987 raider timing mark location - Google Search

timing marks on crank gear mark with white chalk so you can see with a timing light dont belive tensioner is adjustable Chiltons Repair book for head gasket. out of water? where?

wrong timing, if it did it when you bought it, shame on you, take it to a certified dealer and let them fix it

the look up info is marked 3.0 L, v6, S , FI, im taking , the S = it's a single if you open the hood and look at top of motor there should be a logo in middle of motor.

You could also have weak coil pack(s). Weak fire will cause misfire, backfire and bad idle.

you will need the OBD codes read as could be a few things this will pinpoint the sensor(s)/switch etc at fault keep me posted

sound like bad turn signal switch.

Sounds like a tire pressure light, check all tires are full and up to spec :)

A bad flasher would not usually cause no brake light, the problem you are discribing sounds like it could be a bad multi function switch, that is the turn signal/hazard switch, everything you have that is not wrking, goes through that switch on most cars. Would need to look and a schematic to make sure and do some voltage checks, but that is the direction I would trouble shoot it in.

What would you like to know about your starter?
