Will the car s ECU will fail due to the lose connection in distributor to spark plugs?
I cleaned the spark plug wires that cones out from the ECU and cleaned them. Once I connected the wires back and start the engine, I noticed that the engine is rough on idle and suddenly engine turned off. So I again checked the wires that I cleaned earlier. Turned out that 1 and 4 spark plug wires were not connected properly. So I reconnected them and tried to start the engine, but its only cracking. Further checking, I found that I'm not getting any spark from the spark plugs. I'm worried about ECU, so any advice is appreciated. My car is Honda City 2001 Manual.
Likely no. Although the Distributor might be shot. Pull the cap and check for burn marks in side the contacts and on the rotor.
Have the car towed to a shop and show a mechanic exactly what you were fooling around with and pay him to put it back together correctly. After this please never, ever open your hood again.
Plug wires aren't connected to the ECU, they go to the distributer. Not connecting them properly won't mess up the ECU. Maybe the rotor in the distributor or the cap contacts are worn so bad that the spark is jumping to ground on the rotor centerpost.
You cleaned the spark plug wires? I can't envision just what all that entails.
- What are signs your car needs new spark plugs? I have a newer Honda with 75k miles. It started making loud noises in the morning and seems to be running rough like not accelerating as fast as before. I have read that Honda uses NGK iridium tip with 120k mile rating. So should I wait til 120k miles?
- Spark plugs covered with oil plus exhaust smoke? Just got the carbs cleaned and working perfectly on my 82 Honda Nighthawk 450. I started the bike and just a moment later there's a white smoke coming from the engine and exhaust. I took the spark plugs off to aid in addressing the issue and I have found that there's a black oil on them. Anybody have an idea as to what's going on here?
- How to read spark plugs over time? I know how to read spark plugs but over time, would a reading be accurate? Have a Honda whose spark plug is maybe 2 years old, would its reading still be similarly accurate as if it was only after a first good week of use? Stock everything, the porcelain is black, I'm upjetting now with a aftermarket exhaust and filter, should I upjet with if the porcelain is black? With the length of time? Should I try a new reading with a new plug? (Already installed one)
- Can i used another car models spark plugs to my car? I have sparkplugs for a toyota avalon V6 And they fit on my honda accord I want to know if i can use them Will it affect it mechanically
