93 Civic Si/B16a swap - Running rich and engine rpms rise but no acceleration
so i take my car to the shop. I tell them it runs rich low idle.
93 si
b16a obd1 no mods but intake has right ecu etc.. trying to make bard
I take it in and they tell me my tps sensor is bad causing low idle, so i say ok ill just replace it myself. They also mention they will need another 1/2 for further diagnos on why its running rich, but i tell them no its ok ill just replace the sensor and bring it back when i have the money . So i drive my car and i swearrrr once i stepped on the gas my rpm's just climb and my car doesnt get on it anymore . I mean my car used to get on it like good response. Now its just hella slow it doesnt get on it.
So i tell them my car lags it and my rpm's just climb they told me they adjusted the fpr would that cause for this to happen??
They said just disconnect it i mean how ? do i even do that would this cause this help please! just so frustrated that my car doesnt run right anymore.

Re: Running rich! Going NO WERE
Is your's aftermarket? Take it back and tell them to put it back to stock settings even though I don't see how it's possible that the FPR is responsible.

Re: 93 Civic Si/B16a swap - Running rich and engine rpms rise but no acceleration
Thats what i said.
So i go and take it back this morning. Tell them i want it back to it was before.
He advances my timing and i get back in my car and it picks up good but still has the very low idle i will replace the tps sensor .
Also they said it maxed out the smog machine because it was running so rich. but once he said "we put the timing on spec" it was 400 more closer to passing emissions, but my car ran like crap when they changed the timing im very stumbled. Could it really be that a tps sensor would take it so far off spec.

Re: 93 Civic Si/B16a swap - Running rich and engine rpms rise but no acceleration
just getting back to this after a while, none of those things was the cause for my car to run so rich
i took it to a reliable shop and they found that the o ring was missing from my map sensor so it was causing alot of vacuum hence to send more fuel
