Honda CRX Stuttering when it is under light stress

This problem started about half a month ago and has slowly gotten worse.

The first week, whenever I would go up a steep hill or have the rpm's low, it the car would feel like it was choking and stutter, but not die. Then, once the rpms got high enough, it would be just fine.

Now, the car is a lot more finicky and stutters easier and more often. While the car is idling, I feel the car occasionally jerk like it had a hiccup. I'm assuming this is a fuel line or pump problem, but I don't want to send this old car in if it is going to cost me a grand to repair it. What would the problem be most likely to be, and is it going to cost me an arm and a leg?

Start with simple stuff. For instance, bad plug wires can cause similar symptoms and an EGR valve that is sticking can as well. You can pull off the EGR and clean it. Check the PCV valve.

I suggest spending $20 and getting a repair manual. When cars get to the age that yours is things start to happen and the most economical way to take care of them is to do it yourself. We can help but there is a lot of pride and pleasure in doing it.

Let me know how things are going!

I have a 1989 Honda crx hf, It has 197,700 miles. Recently I started to have the same sounding problem as previous posted. The car would have slight shudder between 1800-2200 rpm. Any speed within this rpm range it would shudder. I replaced the dist cap, rotor, wires and plugs. That did not change anything, and now it seems to be getting a little worse. At hot idle I can hear a miss (putt-putt)out the exhaust. The fuel filter and air cleaner were replaced. I have used fuel injector cleaner and no results. I replaced the injectors with new, no-recons. I checked the compression and in all cylinders with a 10 count cranking and I'm getting 180-185 psi across all cylinders. When it hot it is very noticable-I pulled each plug wire and have narrowed it down to # 2 cylinder. This weekend I was going to pull the valve cover to fix a leak and inspect the cam and set the valves. It is a old car but it is a great gas milege commuter and I'm not wanting to part with it quite yet.I'm openfor any suggestions, Thank you :|

That was going to be this weekend also, Is it just a matter of pulling a vac against it and checking for response?I also borrowed a set of injector noids to see if the injector is getting its pulses. 8)

Good! The EGR should be taken off and cleaned. You might need to get a new gasket or make one for it. They get plugged up sometimes or stiff in movement. Generally a cleaning is all they need.

I removed the EGR valve and cleaned it and pulled a vac against and it works fine. I removed the valve cover checked and set the necessary valves, but basically all okay, cam is okay. Is it possible for a distributor pick-up or coil to do this? Also a vacum leak?I was going to do a leak down on the car but the compression is good and doesnt lead me in that direction. I install the injector noids and they are lighting. Also this car passed a smog test 1-20-07. I was also wondering about a sticking exhaust valve stem? If I take it to a shop would a occiliscope pick something like that up. Thanks?

I have a 1998 Civic DX 1.6l SOHC with 80-90,000 on it. I parked my car because of a somewhat similar problem, Accept mine knocked before it puttered. And it would lighten up around 2,000 rpms or higher, then one day it was constant. I spoke with a motor shop today and he said a misfire was being caused by anything in the ignition. So I am trying to narrow it down, but I don't want to just start replacing things that are perfectly fine. Any other idea's? Any help would be great, I also heard to upgrade the Coil to an External MSD coil to better the amount of "juice" getting to the spark plugs. Is this true? Thanks

Cravin,

You mentioned you narrowed it down to cylinder #2. Try a different wire on it? Check the plug to see if it might be cracked? I doubt the pickup and coil as you have stated that the others seem to fire fine. Points to cap, wire, plug. You looked at the valves and you mentioned that the compression was fine right?
