While driving car itll randomly start bogging down/cutting out. If you floor it, it starts getting back to normal(not completely) but when letting off it happens still. I flip the key and it starts running normal again. This only happens maybe 2-3 times a day with normal city driving. doesnt happen on highway. Also feels like throttle response isnt where it should be.

Ive recently replaced TPS, fuel filter, and put a new(used walbro 255lph fuel pump in and still continues to do it.

breakdown of car:
90 Integra Ls
B16a swap(obd0)
crower built CTR head
header-full exhaust
AEBS power plus intake mani

i was thinking maybe bigger injectors(310s), or the fuel sending unit?? NEED HELP ASAP.

 

checked for codes? remember, on obd0, to check the led on the ecm for a code flash. KOEO.
if no codes, first place i'd be looking is ignition. does the tach act irradically when the problem occurs? if so, problem is likely the igniter. if not, buy an HEI tester and follow the instructions supplied. super easy to use and cheap as dirt. this unit actually stress tests the ignition system. if there is a fault in the ignition system, the HEI will expose it

 

tach acts normal and no codes are being thrown(not sure if CEL on tach even works) but ill be sure to look into those. think a different ecu would help?

 

not if it isn't the problem. what i mean is, test first. replace second. there is no indication that the ecm is the problem. the components of honda distributors are extremely common to failure. especially through the symptoms you've described. start with ignition, bud. HEI test it. even if it isn't the problem, the HEI tester is worth its weight in gold for future diagnostics

 

what do you mean by this statement?
and you actually checked for codes? regardless of an illuminated cel?

 

gotcha. oh and the icm in the dizzy was replaced as well. but other than that, the distributor is newer.

 

i have no idea why i said tach lol, disregard that.

 

did you check at the ecm led with the key on? if there is a code, the led on the ecm will flash. the CEL is irrelevant
