i got a 92 cb7 with a 98 h22a sir engine. im wiring up the EGR. I got a wiring schematic for a 93 prelude. is the wiring the same for the EGR for the 98 as it would for a 93? when i installed the engine i dont think i wired it up correctly.
since the shares the same wires as other sensors. its throwing it off with the wrong wiring.
at the moment the car is getting not so good gas mileage.
i got all most of the vaccumm inlets on the intake plugged.
i idle is set at 800 and when i start it up. the rpms go up and down and after a few mins the idle goes steady.
and sometimes when i drive the oil pressure light on the cluster blinks.and at stoplights or when i stop it sometimes shuts off.
really could use some advice thanks alot!!

 

ok as far as the oil light coming on and shutting off car thats the oil sending unit going bad or is clogged up. as for egr i have a 96 cd5 and l just plugged mine right up like stock. ur connector should be the same if not i would check ur stock egr to see if it mates up.

 

Well my old engine i got rid of it.
the old connector for the EGR is more square compared to the OB2 plug that is round.
my accord is a 92 so its OB1
Oil sending unit going bad or clogged? i'll def work on it and see if its clogged.
Could this damage the engine at all?

 

ok here's a update. i rewired the egr from some diagrams. now im getting a cel 3 and 5 for a map sensor.
dont get it i wired in the map from the books wiring schematic.
any idea's? also running the accord ECU til i can get a P13

 

ok then thats alot of issue running accord ecu which l am also. u cant get full potential of motor with that ecu. and l would try a different diagram. didnt think about obd 1 n 2 (brainfart) if l was u then l would just delete the egr. they make delete plates for egr and u are lucky u can do this cuz ur obd1. l would do that and solve problem easier. by eliminating egr and using a blockoff plate in place of egr

 

yeah i think i'll just get a plate for it though.
but what is the real head scratcher is the gas mileage im getting.
i filled it almost to the fill mark and went 35 miles and it went down to 3/4 of a tank!!! i hooked up the map sensor that was on the intake and suddenly it started to run horrible. i tried using the other map sensors and it doesnt run bad but nothing towards the better. i really dont know what else to do

 

anyone got any ideas?

 

its the wrong ecu and engine mapping. u have to have correct ecu,also if u have a fpr adjust u may be running to rich. which in long run will be bad. i know l was running rich. only way l found out a friend had one of those bigass real obd scanners with the screen not a actron those things are ok but not top notch. he had like a matco or something from the dealer. anywayl burn gas like crazy also,im running stock accord ecu with the tcu disabled.l had a p13 and well long story but i recieved alot of help here for my swap and now l can say l KNOW so pm me ill try and help u through some of ur probs

 

Wow Thanks alot!! my dad has connections to Scanners but i dont think it has the connectors for a obd1. he's a diesel mechanic.
i know i def need to get a p13 but man those are so expensive. i cant seem to find a good priced one. is it good to use a p28 chipped?
those would def be easier to get ahold of.
this was my first engine swap. i do autobody repair by trade so alot of this is new to me.
wierd with the jdm h22 it doesnt have a vtec pressure switch. and i dont think it has a idle air control module. i forget the exact name but its on the intake on the drivers side. i just see a plate there.
but yeah man that would be awesome!!!! i'm not on here too much. ill pm you my cell
