Ok i just noticed this today, car was acting perfectly fine, changed oil and was out for a cruise. i noticed that when i get on the gas suddnly at about 35-40% throtel it was hessatate like hell. i mean not even go anywhere and it will just chug everything. i pulled over and everything is connected. car idles just fine and i can rev it to 7k no problem at idle. but when under load it will hessatate for a sec then pulls like a rape ape...im confused...any help would be great!

Cheers!

I had this same exact problem.I did a tune up & still had the problem (I kind of knew i'd still have the problem but did it anyways) so I figured I was either getting to little or to much fuel.I checked out the injectors for cracks and whatnot, they were fine.I knew my injectors haven't been cleaned in awhile so I figured i'd send them in for cleaning but before I went off and did that I went up to murray's and bought a little bottle of Lucas upper cylinder lubricant & fuel injector cleaner for $3.78.I put it in the tank with about a 1/4 tank of gas & drove it on the freeway for 5 minutes, then I got on it.It was a miracle...the car never did that again.Im not saying this will solve your problem for sure cause are problems may differ but it's well worth it.Here's a link so you know what to look for.

i will also vouch for that stuff. used it in the rotary and it didnt do much, but in my subaru when i got it, it was running a lil funny. i put that stuff in and it made it run a lot better. my cousin also used it in his ford ranger and it helped it run better off the bottom.

how old is the fuel pump, it may need to be changed as the pump may not be keeping up with the car any longer , specialy if modded. but if you have a 255lph pump then ya check the injectors.
