Ever since I put this LS in the engine has deal nothing but trouble. In the past...oh...2 days it lost FULL low to mid throttle response. The engine LITTERALLY feels like it's gonna stall (shaking, RPMs don't go up) unless I FLOOR the car. When I floor it, it hauls ALOT of ***. I beat my friend H22 Accord on the way home today but could barely leave a stop sign unless I floored it. The car also idles very slow, which lead me to think the bottom end was starting to loose all it's compression, meaning I get to put my now fixed B16 back in.

Now the kicker, I like to drive my car is the lower RPM range, saves gas, which is over 1$ a liter. Now, if I allow my car to be at low throttle and let it reach 3500-4000 rpm, it will instantly feel perfect again. It's really puzzled me.

I've changed:
- Spark plugs (had spare set)
- Wires (same deal)
- Cap and rotor have less then 10000kms

I've done:
- Set timing
- Checked gap of plugs
- Checked codes (CEL was on about the O2, nothing else)

Things I know are going bad:
- Head gasket leaks like a mother
- Burns about 1 liter of oil for 3000kms if I push it. I add nothing if I don't
- TB idle screw is jammed....bad...

I'm suspecting that the fuel might be the issue. I have B16 injectors (no difference, but still mentioning), fuel rail and the FPR is from a Z6 (no gauge to adjust my adjustable one ). The other is that the motor is just fucked and now blowing up slowly on me. When it was first put in it felt faster then the B16, but it only degraded from there.

I'm really puzzled, I wanna put my now fixed B16 back in I just simply don't have the time to do it right now. I'd rather fix it and wait for warmer weather.

Cribs:
- Car lost all mid range/mid throttle
- Compression still good, hauls *** on full throttle or high rpm
- 90 civic, B18A, OBD1

 

Bump. I'll mention that this only happen when it's warm, and only gets worse if the engine runs for a long time.

Compression must be going on it.

 

replace your O2 sensor and fix the things you mentioned you already know are bad.

Wow great input einstein! Your for sure gonna get the nobel prize this year...

Now for some real input as to what ELSE I can check. I kinda don't want my car crapping out on me at work, 35 kms away from my house.

I knew I shouldn't of posted on HT...

 

Could the o2 sensor cause bogging but THAT bad.....? Damn GL seb, What happened to the ls/v build?

 

i was having that type of problem with my b16a, would spit and shake and stutter leaving from a stop and it was my TPS but it would through a code.. just a though

LS blocks don't rev to where I want it to rev unless I sink alot of money into it. It's just easier buying a GSR block. But money got short, and I decided that painting the car is more important then having a nice engine. The B16 will have to do over any B18 for now...for now...

I'll recheck my code with someone else holding the wire in so I can see better. Plus it didn't help that I checked when I was higher then a kite lol.

Yea no doubt, Im through trying to argue with people who say you just gotta throw a gsr/b16 head on and your good to go . I drove g0crxg0s gsr crx with skunk2 intake mani and some other minor **** and that thing was a beast, pulled hard as fawk. I hear you on the money thing though, I havent put any cash in my car in a while. With my current situation I really cant.

WTF you know the head gasket is bad and you are burning oil why don't you fix your head gasket and the oil burning problem and get a new throttle body to fix your idle control screw which could be causing a vacuum leak making it run like ****. and I'm sure i would win the Nobel prize before you Mr "whats wrong with my car my head gasket is bad I'm burning a bunch of oil what can it be" LOL but you are right your compression is probably going LMFAO. re-read your own post to realize how dumb it sounds no wonder this forum is going to *****. people ask for help and get pissed when they get it.

Hmm...yes....the headgasket is leaking oil, and I'm assuming it's burning oil too. I add 1 liter in between oil changes IF I beat on the engine. Ya, I can see why it would be such a rush to fix it especially on an engine that's gonna be in the car for 2-3 more months before the B16 goes back in. And no, there is no vacuum leak. The idle screw is jammed, meaning it's sealed so tight it won't move. How can it leak? And the engine doesn't have a bad idle either, just low, so it ain't leaking vacuum. Before you make a statement make sure you know the symptoms of it. The engine has no vacuum leaks.

I rechecked the codes, code 41 is the only code (O2 heater). The TB is getting replaced one the one I lent to my friend gets given back to me. I should of took it back 2-3 months ago when I was suppose to but I'm too nice to my friends. I think the compression rings are dying, not the headgasket. Oh well. LS engines are ******* garbage.

and if you re-read my post you can see i didn't say "it has a bad idle and a vacuum leak because of the idle control screw" I wrote "<U>could</U> be causing a vacuum leak making it run like ****"

 

head gasket would be the first thing id replace before anything.. if it startes leaking coolant and you start burning it.. your engine can get screwed up pretty bad..

Coolant level has been the same for the past 10000kms or more (since the engine went in).

I guess the engine is just dying. Searches on here for 'weak engine' yielded crappy result, and most people were saying it was just a dying engine. I guess it's my own fault for buying an engine of my brother.

I'm gonna run a comp test tonight and change my fuel filter and O2 sensor. If none of that works, I'm ******* scrapping the LS, garbage motors in my opinion. So pissed off at my car right now that I just wanna go to it with some lighter fluid and a match.

 

Sounds exactly like an o2 sensor symptoms, low rpms bad power, full throttle good power. I mean if its not that, it would be somethign stupid like adjusting tps sensor, idle screw jammed. sounds like a mess of a motor

 

if the head gasket is leaking oil im going to say its going to start leaking coolant next. just because you have a problem doesnt mean you should jump to conclusions.. it could be something as simple as an o2 , but you should replace the head gasket before it gets worse.. and you shouldnt have to worry about buying an engine from a family member

 

Well last night I got fed up and ripped off my dizzy. IN my horror I found the inside of the cap was missing its gasket. Everything on the inside was rusted to heck. The cap was rusted to the shaft so badly that I had to rip apart the dizzy fully to get it off (by pulling the shaft out). I cleaned up all the connection, replaced the ignitor, cap and rotor and voila, the engine was good to go again (still felt gutless but adleast it was responsive). I guess the previous owner of the dizzy must of gotten lazy on me. It was the first time I opened up the dizzy since I bought it. Now it's running good enough until winter is over for the much healthier B16 to go back in.
