Hey EF's Lover!
i can't seem to figure out what wrong with my LS Crx. It bogging alot and when i step on the gas it won't want to go. When i drive black smoke come out like crazy. My car is eatting too much gas also. Im running an :

94 Integra Ls motor
obdo pr4 ecu
d16a6 fuel injector

 

Any codes ? Sure the tps and map sensor are not switched ?

 

my car isn't throwing any code

How about the map sensor and tps, you sure there in the right spot ? And if they were switched around, the check engine light still might not come on.

 

im not quite sure how to check those. im still a noob at this

 

timing belt slipped...happened to me...new motor time...exhaust valves are bent..or distributor is dying...

 

why are you using a6 fuel injectors?? try using 90-93 ls injectors. check your timing also

 

im guessing your spark plug wires are switched around and isnt in the right order?

 

that sounds about right ^^^^^^ but it could be something else...

 

was it running good at anytime and then started to **** up, or is this a fresh swap?

 

same hting is wrong with mine, mine has done it since the fresh swap, sorry to budge in like this, but id like to know what it is also. bos out when i floor it or when i double clutch it. ive been told it can be timing belt. but i guess the tps sensor and map sensor could be switched, some one got any pics? it would help me and my friend who posted this topic out alot. thanks. and good luck

 

pull the vac line off the fpr if there is gas in it replace the fuel pressure regulator as that is most likely your problem

 

plug wires ... at least u should pray.... go check firing order in FAQ section and make sure there on right order. Also pull the plugs outa the head and look to make sure the metal clips that connect to the spark plugs r still in the plastic (trust me)

good luck dude, get back with us

 

Fuel Pump ?

 

you are probably running rich because your fuel injectors are running too high. if possibile, try putting the stock injectors back in. if this solves it,you've found your culprit.

 

Its not going to be the injectors the injectors are the same between the LS and A6

I would say check your firing order and your timing...

are you serious??? i think you've watched the fast and the furious too many times. sorry, don't mean to get off topic but i can't believe someone actually said double clutching.

anyways back on topic. do you have an adjustable fuel pressure regulator?? if you do and you've bumped the pressure up too high your car will run rich, causing the black smoke and also at low rpms it will feel like it's bogging down.

 

ok i will check the timing and distributor. cuz i know my engine is misfireing and oh yea i notice my engine light just came on also. it didn't b4, but after i drive for 15min. then it will come on . THX U GUYS!!!!!!!

 

So much guessing and miss-information going on in this thread.

If your plug wires were switched around, it would always be running rough.

Here are the wire colors for the tps and map sensor

TPS Sensor Wires:

1 Red/Blue
1 Green/White
1 Yellow/White

MAP Sensor Wires:

1 White/Red
1 Green/White
1 White

If you switch these plugs aroung, at idle the car will run fine, but as soon as hit the throttle, the car will bog.

werd, that is correct info. I still would check timing and fuel pressure after if the plugs being switched didn't solve the problem. BTW what code(s) are being thrown?

 

Hey guys, i checked the timing belt and i don't think that the problem. I adjust the valves alittle bit and it run kinda/somewhat better. Yes, my engine was a fresh swap. how do i adjust the fuel presure? and fire order??
