i have a 99 ex and just put in a b20 w/b16 trans using the stock harness and a obd2b to obd1 harness. im using an ls ecu.

car cranks over and starts, but will not idle. it runs like **** if it runs but you have to hold the throttle about a quarter open. fuel pressure is like 44psi, stock injectors, its an 96 ls distributer with a adapter to the ex engine harness. i have spark and fuel.

i pulled the plugs and it looks like cyl 1 and 4 are lean as hell where as 3 and 4 are black.

think this could be bad injectors? maybe a bad ecu? im out of ideas and need some help

 

yeah i had a very similar problem with my 97 civic ex. Be sure you check your fuel pump pressure again and also you might want to check oil pressure and levels and alll that and finally you could check the IAC valve, if its all dirty and **** just spray it with carb cleaner really well and put it back on.

also maybe your timing is off too

 

also make sure you dont have the tps plug and map sensor plug switched.

 

i didnt think i did, but now that you mention it, im not positive.

the iacv is brand new from honda and clean. ill triple check the timing.

thanks guys!

 

also check if you have all the vacuum lines hooked up with no leaks.

 

wow a brand new iacv? thats weird that you're having a shitty idle.

maybe you should check your ecu out to see if its telling your car what it should be you know

 

is the idle bouncy?

 

you sure the dizzy is the correct one?

 

fixed it today. as it turns out, the dizzy was bad. i swapped it out for a known good one and it started right up.

 

job well done my friend

 

was that all u did?? i have a ek b20b swap and it starts n dies imm after starting. i have tried everything but it still dies right after starting
