HI All
Thanks in advance
1990 GMC Suburban
Vehicle has been running smooth no problems except it needs new
exhaust from muffler out. I'm wondering if this has to do with my
current problem.
Started the vehicle yesterday and it ran rough, started down the road
and it felt like it wasn't running on all cylinders. Very noticeable
expecially when first starting out. I turned around and parked it
after a 1/4 mile.
Where should I start?
Thankyou
Ross

With the little bit of info you've posted I would say that you need to first
get the computer checked for error codes. Could be anything causing your
problem. The exhaust I doubt has anything to do with it.

Check the dist. cap for moisture and wear.

When it's acting up, look at the injectors for low or non-existant flow.
Had a similar problem on my 1990 and couldn't locate it until it threw
me a "lean" code.
