My Car now started to hesitate and bog under accelaration. I noticed that one cylinder isn't firing well. When i unplug the wires to the sparkplug on this cylinder on idle, the engine sound barely changes but if i remove on another cylinder i see a big difference. I bought some kind of stethoscope to check if the injector is working i hear it clicking really well (might be still plugged though). Anyone has any help?.
I know that my Throttle Cable is due to be changed, could this be messing with my TPS and causing the hesitation? The cylinder and bad idle were there since i bought it but the bogging wasn't it only started since it's cold and the cable started to be sticking a bit.

I AM DESPERATE,

Car symptoms,

Idles low and shudders on idle
Bad cold start
BAD gas mileage
One cylinder misfiring
Bogging under acceleration


Things i did
All sensor parameters are ok (according to my garage)
DIstributor cap seems new previous owner changed it
Compression is ok
New Platinum Plugs


HELP me someone I'm tired of paying and still having the same problem.

 

i don't know how many itmes i have to say this: grounds the root of all problems in cars.

make sure your electrical system is grounded properly, and if it is then you might want to get it checked out

 

try the valve cover gasket...maybe its leaking...

 

Have you replaced the wires, they might be the culprit.

 

If the check engine light is on then take it in and have it plugged into the computer. It will be expersive but they will tell you exactly what is wrong.

 

I recently found a bad injector causing same symptoms. You should check each wire/plug combo to see if spark is ok (take plug out, connect to wire, hold to ground, check fire), then do a compression check on every cylinder. I have seen accords run and idle funny with 170-160-170-170 compression.

The acceleration bog may be a totally different issue. Check EGR runners, and clean them as well as intake butterfly. What year model anyway?

 

is there oil on the spark plug boots? Yes: valve cover set (4 o rings, 4 gromets and v.c. gasket, replace all) No, check the cap and rotor for corrosion/ damage/cracks or signs of any moisture etc. also check the plug wires. start the car in a dark area with hood up and look for sparks.
