91 240sx problems
I tryed searching and couldn't find my exact problem, its a 91 240sx auto le, it just started idling ruff, but the rpm gauge doesn't jump around, its making a loud ticking sound from the resignator, once it gets to about 2000rpm it seems to run good, I didn't know if the cat could be clogged or maybe the resignator is clogged, or if it just needs a tune up, The noise is whats getting me. PLEASE HELP, Thanks

You probably have a dead cylinder. Install new spark plugs.dbentley1989 wrote:The motor is shacking really bad, its moving a lot shacking the hole car, when i rev it it stops running as rough. PLEASE HELP I DONT KNOW WHERE TO START
If the problem is still there, find the dead cylinder by pulling the plug wire off of each cylinder one at a time; when the motor operation doesn't change, you've found your dead cylinder. Connect a spark plug to the plug wire and lay plug on top of the valve cover to see if it fires; if OK, then the fuel injector has a problem.
