my car hestitates but it only does it sometiomes.
first gear it pulls all the way up to 7 but in 2nd/3rd/4th it hesitates after 4500 rpms

i still have the stock fuel pump, fpr and filter but im tuned for 10psi on chrome pro w/ dsm 450 cc injectors and VTEC is set at 4500

just wondering if my fuel pump might be cutting out?

i have a d16z6 stock 90,000 miles
14b turbo hf manifold
2.5 inch downpipe
2 1/4 inch thermal exhaust w/ gutted cat
2.5 inch intercooler piping


msd cap, coil and wires

act stage 2 clutch, pp, and 12lb flywheel

 

could be many things but replacing the wearable ignition parts (cap, plugs, rotor) probably solve the problem

 

i just put the new msp cap/rotor, coil and wires about 2 months ago
