i have a 91 dx hatch with a b18a1 swapped into it and when i start it up it idles very rough like its hunting and surging until it warms up then it runs alright, it is also very hard to get started if its not warmed up. we talked to a guy and he said it was probably the distributor, he said it didnt look like the right one. he also said it could be the wiring job these people did on it when they swapped it, should i buy a teg engine harness?

well i have checked all the valves and everything, my question was if it could be my distributor or bad wiring

 

Any idea what distributor you have?

 

no but here's pics, the guy that looked at it said it was the wrong one and im pretty sure there is only 1 bolt holdin it on

 

there should be a td-??? stamp on the dizzy to help identify it...!!!

 

its td-22U

 

td-22u is a first gen b16a vtec dizzy and you have a b18a1 non-vtec motor...!!!

 

okay the guy i bought the car from said it had a vtec dizzy in it, would that be part of my problem? what dizzy should it have?

 

td-24u

 

well assuming you are running obd0 still then that dizzy should work fine. aside from the obvious lack of bolt holes lining up to secure it properly. if you're running the engine with an obd1 ecu however then that distributor will not work. and to answer your question your first post, no should not buy a teg harness. if you need a new engine harness then get another stock dpfi harness.

 

alright thanks ill look for one

and its a chipped p28, i dont know what obd it is the guy i bought it from didnt know a whole lot about what it was he just swapped it in

 

p28 is obd1 and your dizzy is obd0. there's your problem.

find yourself an obd1 92-95 ls distributor.

or change that ecu out for a stock obd0 pr4 and run the dizzy you have now.

 

alright so ill find that obd1 dizzy if i can

 

Thank God for distributorless engines! lol

 

lol yeah, also the car is extremely hard to start, im thinking its something to do with the injectors? it has had different injectors put into it and the resistor box definitely isnt where the stock one should be, could that be the problem? a bad ground or something?

 

Different injectors, what the fu*k?! Swap them out for the same size!

 

sorry i think you misunderstood that lol, they are bigger injectors, they are all the same.... i just dont know exactly what kind they are is there any way to tell?

 

i have the same problem in my car but idk what dist it is but it is running stock computer on doubled up titamium valve springs/retainers low comp pistons header eagle h beams and all arp studs and an msd a6 and i cant figure it out sometimes it idles at 800 rpm just like its supposed to but most of the time it just surge idles from 1000 to 1500 and when its cold it hates starting and when it does kinda kick over it sputters super hard and then it has the honda surge idle 2000 then into its idle up and down oh it is also a 90 crx hf and i bought the car like this... if anyone could help it would be greatly appriciated thanks guys
