Just letting you guys know that after the fuel pressure fix, my mileage has gone up to 15.2 mpg in the city and 19.7 on the hi-way. Also, no more false MAF code (p0101), on hard accel.

I sure am thankful for this forum and the guys that have spent their time to help others.

Thanks

 

Can fuel Regulator be cleaned on my 98 blazer 4.3 vortec? Filter (Fuel) changed big difference observed but after car sits for an hour or so it still starts slow, as if it has lost fuel pressure. Turn on key while listening to fuel pump to stop running and car appears to start better.

 

Welcome.

You may be used to ask or some other sites, we dont do the lame crap they do. That's why a search brings up their threads but you cant find the question and answer without jumping all over the place.
