Hello,

I need a new cat and was wondering if a 2" would fit in the stock exhaust pipng of an 87 hf carbd. thanks a lot. i measured the pipe it seemed like it was ~1.5-1.75

I bought my car for 50 dollar had a shit load of problems is still idles a little high but i started to drive it. filled the tank and noticed tha tth eneedle hasnt dropped i drove 100 miles so far. but when i turn off the car the needle goes down and when it turn it on it goes back up. is the needle fawked up or what do you guys think

My car idles at 2k all the time one problem second problem is when the eninge is hot and i turn off the car take the keys out the car tries to turn on by itself.

The belts would move and it would make this sputter sound like its trying to turn on but it cant the engine would shake and the exhaust would shake and then after some time it stops. sometimes its only for a second some other times it goes one for 30-45sec it dependson how hot the motor is or at least that wut i think... pretty weird problem and knda confusing if anyone knows wut it could possible be. im thinking maybe extra fuel getting dumped in there somehow its a wild guess its my first time working on carbs im trying to learn. if someone can help me in anyway that would be cool

Does anyone have a few picture of their carb with the vacuum lines hooked up it would be greatly appreciated. I know about taking out most of the vaccum but im trying to pass smog in california. if i was to take out most of that stuff would it still pass? basically egr wont work if i take out all that stuff rite would the nox but it wont effect hc or co rite so if i was to get a newer cat the 3way obd2 version that take can also take care of nox you think i would be able to pass?

I bought this crx long ago and didnt really care for it but know im in need of it. my integra broke down plus cant pass smog. and know i got school starting on wednesday with no car and no job to pay for fixing any of em lol. the crx was an abandoned car so it needs to be registered and smogged in order to legally drive it around so my goal is to pass smog thats all.

so i have this 50 dollar crx i got it to run. the car idles at 2k i go take out the air cover thingy and this is hard to explain but basically the thing that turns the choke plate doesnt allow it turn to open all the way or doesnt open correctly. it allows the choke plate to open slightly when you turn it on but it doesnt allow it to open all the way. there these wires that wrap around and are mangled but basically its hard to explain ill try to get a picture up later on and you guys can tell me if this suppose to look like that or not. but it looks rigged.

so if i was to hold the choke plate open by hand. it would drop the idle down to 1500-1400 or so and if i was to gas it a little it would drop to 0 and the car would turn off/stall. but if i leave it how it is with the choke plate almost closed partially opened idling at 2k and gas it the car doesnt die. but it seems that only if i am under 2k if i gas it it would die.

at 1500 the exhaust system moves a little and sounds like its slightly misfiring. one spark plug stick out a lot farther then the other i believe the owner before crossthreaded the spark plug threads and the spark plug can not go in all the way. that could be a reason why it misfires rite? because i believe it misfires its hard to tell. could i pass smog without dealing with the idle problems?

can you guys please help me out im in need. i was thinking about getting a carb from pick n pull throwing it on or what do you guys think i should do or check thanks.
