Car smokes and has a terrible dead spot any ideas??

Asked by Oct 31, 2013 at 07:50 AM about the 1997 Saturn S-Series 2 Dr SC1 Coupe

Question type: Maintenance & Repair

When at idle sometimes the RPM's
tend to bounce a little bit like it dies
out for a second and goes back to
normal. Also when I'm just driving
normal the car seems to be perfectly
fine. Like on the highway for example
I can drive to work 40 minutes at 65
mph and it never skips a beat. But
when I try to put a load on the engine
it just wants to bog down mid range.
When it starts to bog down if I put
the peddle to the floor it'll pull good
and run fine. It seems to do it the
worst between 2 grand and 3 grand.
My buddy supposedly rebuilt the
entire engine had the head done and
everything before I bought it off him
so I'm kinda annoyed I'm having
these issues with it... But like I said it
seems to run fine when it's floored.
Took the plug wires off. There's no
shortage of spark there.. Not sure
what to do...

Check for a dirty throttle body, and or idle air control sensor. Clean the carbon with throttle body cleaner found at most auto parts stores. Dirty MAF = mass air flow sensor, use electrical cleaner or special CRC MAF cleaner. Check youtube on how to perform these tasks.
