Hello Guys, please what causes a car body to vibrate, especially when i slow down the car and the RPM goes below 1, but stops vibration when speed increases

Your car is auto drive, when its in neutral or park it doesn't jerk, but when you march brake in hold ups or slow down in rough areas,while gear is in drive, it vibrates or jerks.
Engine goes off mostly when your AC is switched on,especially when headlights are on.

Is this a true reflection of what you experience ?

Solution - just change plug cable completely with the head.

Note: Check your plug cable first if one isn't seating well.

Thats all !

Idle control valve issue .clean and service the idle control assembly .And do general servicing on your throttle body .
The idle control is the mechanism that allow free flow of air into your engine at idle state .Engine performance issue tends to happen when it is clogged up with dirts and you can easily isolate the issue to Idle control mechanism since the issue occurs at idle.

thats almost a true reflection of my predicament except for the car going off when AC and headlights are on.

Plus the plug cable and spark plug was changed barely 2months ago.

Please help a brother.

it seems you drive a Nissan car, the solution is still to change the plug cable and cable cap to its own model, the one there is not its own or damaged within. One cause for quick damage is gap between cable and plug, check cable daily.

Bros on what logical basis are u making this recommendation? there are hundred of reason why I car will exhibit this same symptom .Treating of symptoms is tantamount to recommending panadol to a patient that has fever instead of treating the real reason root of the cause of the fever .
Moderns Car are equipped with self reporting intelligent computer system(OBD2) that can report any issue they have .what is needed is to acquire yourself with the right skillset to understand how this system works and tools to troubleshoot this issues instead of using Kazeem trial and error approach which will lead you nowhere .

Well.. If it's a nissan altima, you might want to have it checked for intake manifold gasket leak.

You'll have to have your car scanned to avoid working blind

I have experienced this problem twice. The first one was solved by replacing a plug coil (ignition coil) that has gone bad. The second one was solved by cleaning the injectors. A proper diagnosis will help your mechanic isolate the problem
