Start with a compression test to determine if there is a weak cylinder or imbalance . the stalling could be fuel related... check pressure and change the fuel filter. more info is needed...... lots of vacuum lines and emissions controls, are the all there? is there a vacuum leak somewhere like the intake, pcv, throttle body or plastic tee?

SOURCE: vehicle shudders and sometimes dies. It shudders

Check the EGR Valve for stuck open condition with a vacuum pump.

If at idle you apply vacuum and it gets worse and shuts down or shutters, then that's not the problem. But, if you apply vacuum and there is a leak, there is a bad EGR valve on the car. If you apply vacuum and it operates the EGR and there is no change then the EGR should still be removed and the pintle cleaned, or a new EGR Valve should be installed.

Also, a coil pack could be causing this condition, where not enough spark gets to the spark plugs.

Is this a 4 tech or quad 4 engine?

Also, the cylinder head gasket could be burned through and allowing one cylinder to bleed exhaust to another cylinder on the Quad 4.

Good luck with this.

Suzuki swift used to tick over at 800 revs, now ticking over between 600 and 800 revs, engine shudders a bit


which engine, what year.?
egr struck open , partially is #1 cause of low idle
and never getting a tuneup.

the ECU, does all it can to hold 800, hot, all day,no matter what.

will fail if:
1: not tuned up, called misfire. (shudders is misfire)
2: too lean (low fuel pressure.)
3: leaking injectors, more misfire. (or clogged)
4: egr stuck open a tad, or stalls if open fully.
5: ISC stuck closed.

Check that the intercooler is in good condition (no cracks or leaks) and the hoses are tight at the hose clamps . Next talk to a diesel pump repair specialist as you may have to re-tip the injectors and re-calibrate the pump for the extra air that the turbo produces. Check that you have the correct turbo for the diesel

I have a 2002 Lincoln LS that up to 3000 rpm seems to run fine. at 3000, it starts to shudder and miss. any ideas/


If one of the engine components is acting up, you should get a check engine light and have codes for the components. If the light is not coming on, it could be a suspension or mechanical problem.
Low fuel pressure could also do it.

I don't know if it would cause the shaking and vibrations, but for the smoke it could be loose nuts or broken studs on the exhaust manifold -- when engine is cold check each of the nuts (there should be 8) to see if they are loose or missing/broken; you may have to remove a heat-shield in order to gain access

95 Landcruiser Turbo warning light comes on under heavy load


If you are "lugging" the engine, you will get increased exhaust temperature (EGT), this will trigger your "turbo" light(not a good thing), ideally you should have an aftermarket "pyrometer" fitted to your car, this will show you the optimum revs etc you should be using in any given circumstance.Or revise your driving technique, ie change down gears earlier.
The turbo should be idled down after long trips or heavy towing, this allows the oil temps to stabilise and turbine speeds to stabilise, thus idle for 2-5 minutes.
