hey folks. im new to the site and hoping you guys can help me out, i have a 93 prelude si with the H23A1 motor. i have had the car for about a week and it ran great when i got it. yesterday the throttle started acting weird and pulsing sorta while trying to accelerate. progressively got worse and now it dies at an idle and i cant get the RPMs to climb hardly even in neutral. any ideas/suggestions?

also my brother just came to look at it and he is a pretty decent mechanic if you ask me and he thinks it might be a vacuum leak. if thats the case how do i test that/find it?

A vacumme leak test someone on the site is bound to know goodluck with your lude

I'm addicted to S/C porn!!!

all of my sensors are pluged in and yesterday idled fine when it was hot. this morning while it was cold it kept dieing while idling. as well as really hard to start. its getting worse and worse it seems. any amount of throttle kills it unless i just tap tap tap tap until it stops bogging and then dies when i release the throttle.

turned out to be a bad fuel pump. lol but shes rumming great again
