Need Help

I have a 95 q45, the check engine light has been coming on periodically but now it's on all the time. It's idling rough and it's sluggish.

It could be any number of things but I'll take a stab and say you've got a dead injector or two. Start by ohm testing the fuel injectors and knock sensors. Easy stuff.....It will only take you about 10 minutes. Try it with the key off but you may have to turn the ignition to the ON position to get readings. The cluster of connectors you're looking for are on the passenger side of the intake manifold.



Once you've ohm tested injectors and KS it wouldn't be a bad Idea to read the ECU codes. Your 95Q is OBD1 so follow those instructions. Auto Zone won't be able to help you pull codes.

I'd also suggest spending a couple of hours reading up on your Q at Q45.org. You'll be enlightened:

Let us know what you're FI and KS readings are and we'll help you diagnose from there.
