98 blazer Lt

stalling if i sit at idle to long and when iwas driving on the highway at 70 mph it kept bogging down .but was fine at under 50 mph.some times i get a strong fuel smell .

search for cpi
check fuel pressure

Probably your nut kit or fuel regulator. Search in the forum for CPI or Nut Kit replacement.

Guys, this is a 1998, it doesn't have a nut kit or a cpi injector.

William, how long ago did you replace the fuel filter or do a tuneup?

Indeed, there is no CPI in a 98. The Gasoline smell could be bought on by a missfire, dumping raw fuel down the exhaust. I am with BlazerLT on this one, do your basic, complete tune-up, all new air and fuel filters - stick to OEM GM AC/Delco parts for your wires, cap rotor and plugs, and see what happens. :) Do it soon too - it probably will not be too much longer before the catalyst and/or an O2 sensor shows problems from the heavy fuel enrichment.

Sorry, read the year wrong :uhoh:

Could also be a plugged EGR valve is if you get on/off surges with gas pedal at steady pressure.

What do you usually change when you do a tuneup?
