#1: fed up la Author: chriseunos,

My car during day time will not let me rev high and it will misfire at high rpm. Im really fed up already. Using the diagnosis machine, 3 problems popped up, fuel pump relay, O2 sensor and idle actuator. 2 of the problems are expensive and i really dont have that much money to fix it.

Just changed the engine recently due to broken crankshaft and now all these problems. Aiihhh...Im really fed up with the car. Sorry, just wanna express out my feeling.

i found any symptom. Whenever i start to rev high, the temperature indicator will slowly drop to the blueish area. Bear in mind my meter is an M40 meter, therefore the temp gauge and the tachometer keeps on flickers. If i press any further, the car will misfire. Now there's another new problem. After misfire, my car will run like shit.

When i press the accelerator, its like not enough fuel to the engine. Once i stop the car at the side. It seems like the engine is running on 4 cyclinder. Uneven rattling of the engine. I turned off the engine. The engine is fine again until the next misfire.

Helppppp

m40 meter means its calibrated for 4 cylinder tacho reading...flickering may mean that you have grounding and contact issues on you cluster...as for the misfire...DME issues.try someone elses DME...maybe you can trace from there.

Problems solved! Misfiring gone!! THe muthafu*ka pulled like a train!

problem? Apparently the socket running underneath the engine manifold is having some difficulty in connection due to particles such as dust, dirt etc etc. I was inspecting the engine last night and wiggled the wires, suddenly the engine just died off. No problem in starting up the car, then wiggled again, the engine almost died.

Today, went to workshop and borrow contact cleaner, sprayed to the socket and other connectors as well, ICV, AFM, brown socket..whatever la! start the car and took it for a test run, ITS ALIVE ITS ALIVE!! I CAN REV WITHOUT MISFIRING!!

not for long bro, although the car now can rev freely, after hard rev, the car is like having fuel starvation, if i let the car idle, the car wants to die off, if i press the throttle, its like slowly going up and misfires. I suspect is the wires on the switch that are bad or corroded...aiyoh...

err.. where's is that la bro? IMHO, u should fix the basic problems first i.e. leaking / harden hose etc. Replace the normal wear & tear. And after that you can slowly diagnose for actual prob.

I saw u holding the AFM. Try to move the 'flap' inside it. If it's a lil' bit hard or not smooth to move, then that's one of ur problem. You can also try to 'de-carb' the engine. Who knows the carbon has clogged in there.

You don't like the shop? Ask me or Highwaystar. We try to help u out. Good luck =)

the shop is at bandar puteri puchong. i've tried moving the flap, it is smooth and no problem. THe mechanic is a great guy to be honest.

I was checking the engine bay and saw that the rubber elbow connecting to the AFM from the manifold kinda in poor condition.

I truely believe that it is an electrical problem. I have no problem revving the car, but after i rev the car really hard, the engine will struggle, its like running on 4 cyclinder only.

I turned off the engine and start it up again, then its fine again...hmm...The problem will occur again when i rev it kao kao again. T_T

Wow... you so patience oledi... if i were you, i will buy RM10 petrol and light the car up...kekeek.. sorry, just to lighten you up larrr...kekeke

Okay, mmm let see...Motronic
Please check Rotor Arm (might be worn out)

Spark Plug Cable (check cable properly or borrow from friend to test)

Spark Plug (might not reliable to your engine. I'm using bosch super 4 but my mech told me to change it because it doesn't suit to my kinda engine)

You convert your engine... check all wiring, are they properly sealed?

Elbow tube (after AFM, see got leak or not)

Thats it for now, we try to find answers for you

Cheers!

checked the rotor arm, no problem

spark plug cable havent change b4

spark plugs are the same as yours, im using W8LCR ones which are perfect for the m20b25

Regarding the elbow tube, it is kinda in a worn out condition. Gonna change it soon

Bear in mind that i think this is an electrical problem instead, the problem will only occur when i rev my car kao kao and the car will act like i'ts runnning on 3 cyclinder...once turned off the ignition and restart it..its ok again until the next rev session
