So i started my car went and got gas, drove it back home and everything was going normal like everyday. Normal driving and normal car running. I left the car on for a couple mintues while i ran inside and when i came back to it to leave this problem came. Studders like it not getting fuel right or something, NO POWER EITHER. My car like studders when revving or idleing and bounces at idle from around 750 to 1000. drives but just has no power only around 3500 to 5500 RPM. studders around all rpm with full throttle. NEED help FAST! PLEASE!

bought it gifts and cant put them on.

 

I use to have the same problem with my mini truck. First things first this is probably what im going to say is wrong seeing as this was the problem with my old truck. Check your efi fuse (electronic fuel ignition). It is probably blown or going out and is just barely getting a connection. But if thats not the case here are some possible problems as well:

1. Air intake/vacuum systems are leaking
2. Fuel pressure/fuel pressure regulator
3. Oxygen sensor
4. Idle air control (IAC) valve
5. Manifold absolute pressure (MAP) sensor
6. Engine management system - connections/wiring/relays

 

You should also check your grounds.

 

you may want to do a compression test, as well, just to see.. it takes 5-10 mins to do, and it will rule out the possibility of your cams jumping time.. I mean, its worse case scenario, but i would check anyway.. they can do that..

How many miles, and has the timing stuff ever been done? I would check all of the stuff that sl0w mentioned, and then check compression, just in case..

 

well it has a B18B in it and that was put on around 10k ago and i put new parts on the motor like timing belt, water pump, and stuff like that. Where can i get my compression checked at any mechanical shop?

PS. someone said that it might just be bad gas that i pumped into it, cause it was fine before i pumped it.

 

why does everyone jump to the big things first, start small like fuel pressure and spark the check cap and rotor, then check fuel filter..then you can rule out other compression and all the other ****..also do u have a check engine light?

 

timing was off. Intake side cam jumped a tooth. been working on it all day outside in the cold.

 

Check your injector screens. My 90 integra was doing the same thing. Problem solved.

 

1) Noob: What are the injector screens?

2) AND: Fixed the timing and it idles smooth and doenst make that funny studdering sound anymore. BUT NOW, it runs but has like no *****. If i were stop go from a stop and drove normal, the rpms drop WAY down, and it feels like it has for power what so ever. Just seems super slow right now. What could it be, cause my dads 91 Civic HB is doing the same thing too. NO POWER what so ever. HELP, PLEASE!

3) No engine light was or is ON.

 

Unhook your injector harness, remove the 3 10mm bolts from the fuel rail. Gentle remove the rail and injectors from the intake. Separate each injector from the rail and look at the top of your injector. There should be a plastic screen in the top of each injector. Use compressed air or carb cleaner-brakeclean. Let me know if this helps anyone.

 

Ok checked the injectors and they are fine. Bought a new dizzy and dist. cap because the old one looked like if they were burt. all black.

So this is what it is doing. It is not reving or driving at full power. At very low RPM it has absolutely no power to get going.

Anyone know where i need to start? Should I check to make sure that the timing is perfectly inline. Maybe it might have moved some. Or could there be other stuff?
