ok i got a new fc, it is an 88 na, doesnt like to rev fast at all, the car doesnt start well, it sutters a bit. i tried pulling off spark wires to see if a rotor was blown and it didnt die so im thinking that means its good, just got problems. there waas no noticable problems when doing so like it didnt try to stall or anything. what do you think?

 

i think its in limp mode, what causes that?

 

Check your timing.

how bout a stuck open injector? it loves to flood out too. if so do you think it would be a primary or secondary?

 

86-88 dont have limp mode, they dont even have a check engine light.

 

thats comforting

 

maybe the UIM or the LIM are dirty? or the TB? maybe the double throttle system is messed up

 

Oh yeah, because that causes the car to flood, right?


Thinking it's a stuck open injector. No real way to tell if it's primary or secondary but you pull them . Are the mods in you're sig this car?

Set TPS, CAS...rawr

 

Perhaps it's a clogged cat.

 

Do you have the cats still on? If so, you can try taking them off and see if it runs better.

Rotaries will run on 2 spark plugs. You can take out the spark plugs and either test compression with a compression tester, or at least listen/feel for 3 even air expulsion noises (not sure what else to say, you'll recognize them).

 

yeah definatly run a compression check on that thing, lol. At least that will tell you if it's anything internal. Once you find out if it's good or bad you know what direction to go.

 

ok the mods are on my other 7. this one is 100% stock. the timing hasnt even been moved

 

Well, the timing not having been touched by you does not mean someone else didn't, at some point in it's history.

Anyhow. Whenever you have a problem, always compression test it before trouble shooting. Spending hundreds of dollars to fix a problem, and then finding out you have no compression on a rotor sounds really bad

Actually, now that I think about it...

When I blew the rear rotor on my GTU, on the 1/4mile drive up the hill to my house, it revved extremely slow also..like, to get to 5000 rpm in a regular NA car, in that time, I went from like 1000 to 1500, and the shifter shook really violently.


Compression test that biotch! After that, do a full tune up. Plugs, plug wires, !!ship out the injectors to be cleaned!!

 

ok, i think its got a blown coolant seal tho

 

rebuild time!

 

could be a jap import engine with rev cut, simmular to turbo versions where the boost cuts out but revs in your case. A $50 fule cut defender will solve your problem

 

lol, doubt it.

 

you can also check the injector clips on the primaries....sometimes the pins will back out for one reason or another....

 

I dont know if anyone mentioned, i think the MOP will cause that if its an S5

 

congradulations you are a moron!
