Ok i know alot about mazdas, but i wanted to move on and try something new. a friends dad gave me a 240sx. so hears the problem im pretty shure the clutch is shot as the car wont even attempt to move untill about 4000rpm but thats not the problem i am having, clucth isnt a big deal, the main problem is it takes forever to the car to start it just wines and wines and then it will finnaly starts to turn over u cant give it any gas until its started and warmed up or it dies and if u try to give it to much gas all at once it dies. it has new plug wires and it also has a belt drivin fan as well as the elctric.

I did all this everything in this area seeams fine its a brand new battery as it didnt have one i gave the car a full tune up the first day i got it. its got me completly confused its also like the throttle isnt responsive at all like u can push the gas slowly and it takes a second for it to relize u pushed the gas.

Sounds like there's an issue with the fuel delivery system to me. Check the fuel pressure and spray pattern of the injectors.

ill do my best to get a video uploded tommarow. so what woul my best bet be to buy a bottle of lucas or seafoam and let it run through a little while. or should the next investment be a new set of injectors.

what rpm does the car idle at? after youve got it started and let it sit for about 5 minutes

actually no that surprised me actually. i was like its having all these problems and no check engine light . im begining to belive the clogged fuel injectors so my next step will be to change fuel pump fuel filter and injectors.
