Re: Misfire under load, and low RPM

I remember an engine code telling me this awhile ago. There aren't any codes stored right now though.

What's weird is that even the exhaust note changes like VTEC does. It'll be revving up slow, hit around 4500, then instantly get louder and I'll get 50% more torque. It's definitely not misfiring ...

Re: Excessive blow by - or something else? Oil in intake.

Yeah I havn't done a compression or leak down test yet. Valve seals are most likely gone.

I don't think this is from the EGR, that would be more of a dry carbon look wouldn't it? This was physically wet oil, not caked on or dry, but still wet to the touch. I'll have to check my venting.

Excessive blow by - or something else? Oil in intake.

When fixing my misfiring problem (couple threads down) I took my air hose off and noticed it was soaked with oil, all the way down to the airflow sensor. The throttle body was also soaked with oil, the plate just coated in it. I took my PCV valve out and it still moves and rattles, but I'll be ...

Re: Misfire under load, and low RPM

Ok the misfiring is fixed. Replaced the ignition wires with junkyard ones, and taped up my airbox hose which was apparently quite cracked. Absolutely no more misfiring at all. New airbox boot is going to be ordered asap.

It still feels like VTEC is kicking in at 4500 RPM. Seriously almost no torque ...

Re: Misfire under load, and low RPM

Hold up - are we talking cam timing, ignition timing, or both? The reason I said it can't (or rather, probably isn't ) cam timing is because with a tooth or more off, you would think that it would run like crap all times - hot AND cold. Mine only does it hot. How would that be cam timing? Ignition ...

Re: Misfire under load, and low RPM

Can't be cam timing, and I don't think its ignition timing either. I just did a test today:

When the engine is cold, at 50 KPH and under 2000 RPM in 5th gear, I can hold it at any throttle position with barely any misfires going on. No bog, just poor acceleration which is normal.

When the engine ...

Misfire under load, and low RPM

My 92 1.8 MX3 has a pretty bad misfire. It's way worse when warm, and when sub 4,000 RPM, and especially under load. What happens is that I'll be accelerating and the car will jerk, and then jerk some more, and more and more and you can hear a defenite miss in the exhaust. At idle, the car will ...

Re: Tools needed to remove e-brake cable?

Used cable was $5 and still works. I take that as a win!

A 10 mm socket, 12, and I think 14mm were needed. Then a screw driver to bend some metal (yay for junkyards) and pliers to pry with. Came right out!

Tools needed to remove e-brake cable?

Heya. Got a 92 GS with an ebrake problem. Only the right side cable works, the left side doesn't move at all when pulling on the lever. I figure it's broken near the bracket, above the resonator. Before I go taking my exhaust out, I want to grab a junkyard cable just incase it is broken.

Since the ...

Re: Stripped threads on balljoint pinch bolt - help!

Hey stupid!

Yeah, I always shoot for the middle. I have one of those non-clicker type wrenches, so the real value is never 100% accurate, depending where the needle rests on the bar and how precise my angle of view to it is. The axle nut called for around 200 foot pounds (170-230 or something ...

Re: Stripped threads on balljoint pinch bolt - help!

Manual called for 43 foot pounds.

Got a junkyard bolt and nut and it worked perfectly! CV axle job is done, and it makes those terrible sounds no more. God, what a pain in the a-- it was to get the old axle out. Ended up using a 2 foot pry bar and.. My foot! Put all I had into it and popped that ...

Re: Stripped threads on balljoint pinch bolt - help!

It seems weird to me that such a crucial suspension point only has a single bolt and nut holding it together.

Getting a junkyard bolt today! Thanks. :)

Stripped threads on balljoint pinch bolt - help!

While replacing my CV joint, which went well, and by well I mean f--- that job, I stripped all the threads of the ball joint pinch bolt when putting it back in. I guess it wasn't lined up well enough, and after the many hours of frusteration I tried to just hammer it in there. Big mistake :(

So I'm ...

Re: Idles good, but after revving, drops below idle & stalls

99% sure it's my netural switch. One guy said this:

You have a switch on the clutch pedal and a neutral switch on the transmission. If either switch is activated the engine computer controls the idle by modulating the idle speed control valve. With the clutch switch broken when you put it in gear ...

Re: Idles good, but after revving, drops below idle & stalls

Ok the rabbit hole goes deeper than I thought.

On the clutch pedal there are two switches. One is a safety to start the engine, the other is to shut cruise control off when depressed. Simple right? Not so fast.

When I push the clutch pedal in and both plugs are connected, the idle drops from 1000 ...
