Car Problems
 

I got a 87 rx7 last week and its done some odd things i wanted to know if any one could help. well it has a cold air, exhaust, the guy said it had bigger injectors. the other day i drove down a littlee back road and stopped at a christmas tree farm, when i tried to crank the car it wouldnt start. I changed plugs and still nothing so my brother pulled me home and once we got in the drive way i tried roling it of and it cranked right up. i heard you could get a tuner or them but heard they were expensive any help? and also the car kinda of skips around 3-4000 rpm it sounds fine you can just feel it kind of stop pulling. im new to a rotory so any help would be nice

well the hesitation at 3-4k is most likley just a grounding problem alot of the rexs here have that problem.
and the no start probably flooded due to the bigger injectors

Get some replacement or stock 450-460cc injectors. Actually the bosch 440ccs would probably work well. does anyone know if theyd fit the stock rail?

how much would they cost would i be better off to buy the tuner?

so is there any way to fix he ground or should i just live with it?
