i have had this car for about three months now, i got it from my sister's boyfriend for $400. I work on cars and i can fix it up, only there is a problem now. I bought it having 192k miles now it has 193k. before, i only had one problem. every once in a while i would get in my car and i would turn the key and it wouldn't start and it would always do this when ever the check engine light is on. one way i solved this was just changing the oil. well it's been doing this more often lately, and it's been getting worse. usuaally i would wait it out and it would take a minute but now it's been taking its time.

The second problem is, yesterday i was taking my friend home, and right when i turned in, the engine started knocking and then the check engine light came on. i'm suprised i made it home. i believe the knocking is timing cause by overheating because i need to change the radiator fluid. or it could be a balance shaft.

COULD SOMEONE PLEASE HELP ME!

 

#1 is the main fuel relay. Very common on 90-93 Integras

#2 it was knocking and overheated? I'd check the head gasket, and make sure the oil level is correct.

 

hm... well thanks! i knew i should have changed the head gasket when i first got it!

 

also would it be possible for the engine to be damaged using supreme 93 octane? i know it says use unleaded only, but i've only used it 3 times.

 

If it's still the stock b18a1 Ls motor then there's no need for premium. All it will do is cost you more. Vtec motors need it, but not an Ls motor. How does the car drive now? Have you driven it since the check engine light came on?

 

nodda, it won't lemme start it at all, i've waited an hour, i'm gonna have to get that relay first. advanced auto doesn't have them, so my dad is going to order it online.

 

If the motor is messed up, that's not the end of the world. B18a1 and B18b are a dime a dozen and very cheap.

 

you could always hit up the junkyard. There's plenty of main relays there. As for knocking it was be more cost effectiven to just gt another b18 longblock they go for cheap on craigslist.

 

kool kool, if craigslist isnt the place where else could i find one?

 

here for sure. Where do you live?

 

you could find a motor at the junkyard, but wouldn't how good the motor is. If there is a auto dismantler near you, you can check there, but a warning tho, then tend to be more costly.

 

i live in north alabama

 

ok today i got the main fuel relay, i put it in. starts like a champ!! but i'm still having a knock. i checked the plugs and the 1st cylnder didnt seem like it was getting any electricity. so i went and got new plugs and wires. changed them, and the knock is still there. any ideas!?!

 

i think it might be fuel injection, like a clog going towards my first cylinder.

 

bump

 

i also have a 92 integra and it makes a rattling noise when i turn on the car. it seems like its coming form the engine but im not sure. is something wrong with the engine?

 

lol yeah most definately, not sure if it's a big problem. i would tell you what you would do but idk if your very experienced?

 

what makes you say that?

 

idk, do you have experience with cars?

 

have you gotten the valves adjusted or tried cleaning the injectors? i know the injectors get really chattery on LS's does the knock progress under acceleration(get louder and harder)??

 

i cleaned the injectors yesterday and it still continued. and no it just porgresses getting faster and faster as the rpm's go up

 

does it sound like a slap or knock or is it chattery, if its chatter adjust your valves its easy on a ls if you go to g2ic tips they got a write up on it if your a dyi guy

 

more like a thud.
g2ic?

 

g2ic.com is all about 90-93 tegs good **** there.

do you have access to a video camera or a cell camers to record the noise and post up here? it might be a rod knock, it might be time for a new motor id just pick up another ls thats what i did for my db1 the old a1 was loud and chattery didnt wanna wait for it to die so i got a b1 free from friend but you could find one on craigslist cheap 200-500 bucks for motor

 

sweet thanks alot!
