ok thanks for that got the code and it is 41 (cat) because its gutted but would that cause a bad missfire?

 

No,the cat.conv. won't cause misfire.However the misfire will cause the catalytic converter to fail.How do you know it,s misfiring?

 

the spit/sputter sound a engine makes when it missfires again it has a full tuneup plus a new dizzy

 

If you are sure that is really missing a cylinder or randomly missing and the full tune up It could be few things including the problem with fuel delivery or the EGR valve( or control of the EGR is malfunctioning) or it could be burnt valve (compression related).What's the milage on your car?
When did the problem started?Just out of nowhere?Was the tune up done for a reason or just trying randomly to fix it? Confess man ! .You know more than we do.

 

mostly highway but 250k

 

Not enough info man!There are several reasons for you cars symptoms.

 

what are the reasons?.....that will help me give me information i have only owned the car for 2 years

 

You gotta follow my questions man.I didn't get any answers yet.(I mean not to my questions)

 

how it all started....driving down the interstate (60 in 4th) and cel came on and went to limp mode put a scanner on it and it was the pickup in the dizzy so bought a used dizzy and it ran fine for 2 days then all over again so i bought a brand new dizzy cap rotor plugs and wires and still missfiring now im at a stand still....

bump

 

i dont want to have and junk this car someone please help a brother out!!!

 

Well, start with simple stuff. Pull the spark plugs, take a look at them make sure they look normal and are gapped correctly.

I had a bad misfire problem, turned out I had the typical distributor leak. It's easy to check, pull out the 3 screws that hold the cap up, and if you see jizz in there you got a problem.

 

new wires plugs cap rotor and oem honda dizzy.....cant figure this one out at all....what would make a code reader not connect to the ecu? my code reader will plug in to the plug under the ash tray but the reader says not connected to vehicle and yes it is a obd2 reader

 

After you changed all those parts do you have spark for all the cylinders?
Do you have a compression ?
Does all the injectors have pulse?
Does the injectors work?
(you can put a screwdriver to each injector and listen to the clicking noise)

 

Check the conditions of where the spark plug wires meets the coils. Maybe there's a crack in them. Also check if your spark plug tubes is nice and dry. Even a slight hint of oil may be bad.

 

just put the "valve cover gasket kit" in along with a full tune up! car runs but has a bad missfire and in limp mode.....i have tryed to hook a code reader to it and the reader said not conected talked to honda and they said the ecu might be bad from the fact the code reader will not connect to the vehicle....

 

That's a hell of expensive guess there at HONDA!Can you get a wiring diagram and see what else is connected on the same wires that are used by DLC ?

 

I think you're getting too hung up on getting the code reader to work. You pulled the codes using the blue connector and a paperclip and got a code 41, right? I believe that's an open primary oxygen sensor heater. Check the codes again and confirm.

 

Double check the ground (G101) on the TB.

 

my '94 developed a horrible miss under light acceleration or when trying to maintain speed. Felt like driving over railroad tracks. Cleaning the EGR ports = fixed.

 

where exactly is this ground strap at on the tb?
