I'm going to pic this up next weekend when the my gas tank is lower in the GS LOL.. I've used Chevron before in my mustangs and Lucas products and can't say anthing bad about these.My mustangs ran like a champ for 150K

BTW i did the DIY yesterday from SeattleGS400 to clean the MAF and TB and i noticed a big difference. I did the TB cleaning 3 years ago but i think it was time since the car hasn't been driven that much in the last 3 years.

I wish i would have found this yesterday before i filled up LOL..

Thanks again Seattle...

I did the Techron additive twice this week as well as cleaning the MAS on my 98. Made a huge difference. I'll clean the TB and air filter this weekend and report back.

Will try first the fuel system cleaner and follow with the cleaning of the MAF and throttle body later.
Again thanks for the elaborate post

+1 sokoyoo, had the same problem but the info from this post really helped out.
