Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

there is a injector driver module relocation kit with a heat sink to mount it to because the module in the orgional location the module would overheat. also check the glow plugs the quick easy way to do this without removing them is to unplug all the glow plugs then hook a jumper wire up to battery positive and and touch it to each glow plug there should be a spark and if there isn't then the glow plug is bad.

The flashing light indicates you have a big misfire that could damage the catalytic converter.. Being you were going uphill (under high load) this would indicate an ignition issue. You may have a bad coil or wires or a bad spark plug. The reason you could only go 30mph was because the computer was put in limp mode. This is a stratagy to prevent excessive damage to components. , Get it checked out ASAP

Just had the exaust filter sorted on my 2005 525d but has started to loose power again when trying to exelerate seems to use a lot of fuel at the same time


Does your car have a diesel particulate filter? Is that what you mean? If so your first question should be, is this the right car for you? Cars with this filter do not cope well with lots of short trips and no 50+ mph runs. These short trip will make the filter full and it will need a regeneration, a high rpm 50+ mph run or a for regen at a dealer. The filter may be ruined already. If so it will dump diesel in your engine oil. The system uses diesel to burn off the soot. If the filter is faulty/ bad this extra diesel will be dumped in your engine oil. So check the oil level ASAP, as the extra pressure from the high oil level can kill your engine.

My Chevy Tahoe has no power and cant get up past 40 mph without starting to lose power, could it be Mass air flow sensor?


Possibly, but it sounds more likely a catalytic converter may need replacing or fuel filter maybe clogged

Why does 2005 Kia Sorento die while driving


If it is a diesel vehicle check the pressure of the diesel pump. It would appear that the diesel pump on this model wears out and it loses pressure. If the pressure is ok there is switch/filter on the common rail that might be blocked. Unfortunately it appears that this switch can not be cleaned but must be replaced. hope this helps.

i had the same problem with my 2002 w3500 and what it ended up being was the butterfly valve for the exhaust brake which is located in the intake just as you take off the turbo line, disconnect the vacuum line on the actuator that goes to that valve and that should tell you if thats your problem

78 GMC losing power


check the fuel pump as well to see if you are getting the right amount of fuel if not the pump itself may run about 20 dollars or so , check timing as well just to see if your off if you have an advance on the distributor and if you go over 40 if it pops back up its the advance {had that problem once before }
