i having a problem with my 1997 b18c. after i open it up when i stop at redlight or stop sign is idles very ruff and goes up and down and the engine light comes and sometime flashes. the car was tuned about 2 months ago since then i chanced the intake manifold and tb but the tunner said there is no need to re tune after just chancing that. i dont no what could be the problem.

 

the intake manifold an TB have a HUGE effect on how the car runs, you definitely need a re-tune. your tuner is a moron for saying otherwise. the cel also means you have other issues as well, and the cel flashing means you have really big issues. jump the service connector and retrieve the codes, that is the very first thing you need to know. you also should not be driving the car at all if it has a cel, especially a flashing cel.

 

i should correct myself it doesn't flash like constantly its will shut of come on but doesn't just keep flashing repeatably, can u explain to me how to check the codes

 

I believe there's a two wire service pin on the passenger side of the car. Should be by the kick panel or lower right side of the glove box

 

and just plug a code reader in it cause i plugged a code reader by the steering wheel and it didnt show anything

 

and i tryed the paper clip in the blue wire and nothing happend

 

anybody got any other suggestions what it could be

 

the blue wire is not the service port, that's an ignition signal output. you need to find the service port, should be a yellow, blue, or green plug with TWO wires. stick a paperclip in it to jump both wires together, with the ignition on but the engine not running

 

and they will be located around the computer?

 

i got it its flashed 7 times

 

Ruff as in dog bark ruff?

 

which means code 7. which means because you have internet you googled "Honda trouble codes" to determine what code 7 is, because I know you're not so lazy that you're spending time typing it out on here but not doing a quick google search :p
P.S., the google search will redirect you to a thread here on HT

 

i know thats its the tps i took the tb of and tryed to adjust it but the most it will go up to is 4.3

 

i put the tb back on and tryed it the engine light doesnt seem to becoming on yet in vtec
but i didnt really fix anything so im not sure what the problem was

 

WOT voltage does not matter when adjusting the tps. 0% throttle is what you need to set exactly.

 

i tryed open and closed throttle but the anyway i would go it would only give me 4.3 so i set it oppaset from before and seem to work abit better i went for a quick spin and no engine light

 

dafuq did I just read?

dude, that's why you have a code 7, either the tps is fried, or its installed wrong. it should not be staying at 4.3v. stop driving the car and fix the thing the right way

 

seems we have a failure to communicate properly.

OP. Use complete sentences as if you are educated so people can understand you.

this also has NOTHING to do with ALL MOTOR/Natural Aspiration engine tech. Either provide us with data that can actually help you, or i suggest doing a bit of research on how to work on cars.

 

Title of thread should have been your first clue haha. But post 16 takes the cake, good lord. Put the wrench down and go back to school!
