I have a 95 h22 swap in a 94 civci si.
running a stock p13 ecu. mods are Intake, and exhaust. And slightly ported stock header.

I only got 70 miles for a half tank of 91 gas.
I have egr hooked up. pep boys o2 sensor was done a bout 3 months ago.
ANd personally the car feels weaker than my previous h22 swap.

i have no codes!

can someone please shed some light on this.
thanks

 

anyone please i dont have a job now and cant afford this kind of gas consumption.

 

clogged cat? how's the idle?

 

do u have a regulator or gauge at least? running rich? it most likely lies on a bad sensor possibly o2 or MAP

 

no cat.

regulatr?
how do i test that

coolant keeps disapearing for some reason.

i have a really bad exhaust smell.

02 is only a few months old.
bosh bought in march

how do i chek the map.
and what does it look like.

idle is ok i guess
moves around from just under 1k to 750

 

timing?

 

You probably need to get that car tuned. Try running another model ECU possibly a p28 and check the results. Dont beat on it, just drive normal

 

isn't leaking coolant a HG problem?

 

i dont think the head gastket is bad.
no oil in coolant
and no coolant in oil

also no smoke. blue or white
