Angry Initial Start...hesitating

I dont know what is wrong with the car. I start it up an dwhen i do it sometimes takes a while for it to turn over (a few seconds). Only once and a while though. an when i start it, it sometimes get lower rpm's and sounds like its trying to stay alive. I have 40,000 on the car so i dont know if its the starter or the fuel pump or what. I just changed the spark plugs and got a new fuel filter.

hmmm. my car hesitates, but i need a new starter. took it to a shop, and they found it had a bad coil. they were gunna charge me 175$ for the starter, plus like 2 hours labor... said forget that, and am going to order one off ebay for like 50 lol.

your problem could be different. i would check the battery first. have it load tested. did you change the spark plugs after you noticed the problem? or before? does it usually happen after letting the car sit for awhile? have you checked for vacuum leaks? you'll likely know if there is one, it'll sound like hissing.

maybe try running some seafoam through it? i kno im due for a seafoam treatment myself. just dont wanna **** off my neighbors just yet lol.

Do you have a supercharger? My car does that exact same struggling-to-stay-alive on start, and it started immediately after I installed my Vortech.

I think it has something to do with our terrible IAC's, my MAF placement, and maybe timing.
