ive got a vu ss ute, at around 2200 - 2500rpm it starts hesitating but only somtimes, its like its bogging out and then coming good, at wot its fine and if im driving like a nanna its fine, it only happens at around 1/4 throttle, doing my head in baddddddddddddd! ive taken the maf apart and cleaned it thoroughly, i dont wanna go wasting a ton of money of this tryn to fix it. anyone had this problem before? im thinking maybe it the tps (throttle position sensor) car is auto by the way.. and i only run it on premium.. any help appreciated!

clean out t/b, IAC check tps.....

what is a iac? ive changed my plugs and leads, new maf sensor also..

Iac = idle air control.. Tin or two of carby/throttle body cleaner does the trick

failing that get your oxygen sensors checked

its idle air control valve. also check your fuel filter and fuel quality

fuel pump ? tune ?

Its only part throttle I can't remember with the o2's and fueling.. I turned mine of ages ago. Is it throwing any codes? o2's is probably the next thing to try.

car is now mafless tuned and all problems are gone! my advice to anyome with a ls1, throw their maf sensor off a bridge. worst thing ever invented! so much smoother and more power and it doesnt idle like a pig anymore, auto shifts good too, myne got done by mail order by apc_performance on ebay for 300$ inc the computer itself! delivered next day! best advice i can give!
