SOURCE: runs rough under load ,stalls

Hi

one of 3 faults

1 MAF sensor also Known as air mass sensor
2 EGR valve, this is most common with the 4000 rev limit and a top speed of say 50 mph
3 air leaks or tears in air pipes or poor seals.

I would be tempted to clean both the EGR and MAF sensor before spending any money though, these parts ofetn work much lonegr when clean

Regards

Dan

2005 gran am Pontiac 3.4 v6 the car is idling on 5000 rpm I replaced the throttle housing gasket and throttle positioning sensor still nothing idling at 5000rpm still does anybody have and suggestions...


500 RPM or 5000? Reason I ask is the rev limiter shouldn't let it rev over 3500 in park or neutral? If idling at 500 then get an external tachometer and connect it to determine that your gauge isn't faulty! if at 5000 RPM it could be a stuck tps or possibly debris in the throttle body or a vacuum leak causing the idle to increase? Is it idling high or low compared to before it became faulty?

Honda element 03. Normally starts up at 1,000 rpm in park and shifts into drive smoothly. Sometimes starts up b/w 1.5 and 2k rpm at idle and JERKS into drive or reverse.Solutions?


Cars not control choke themselves electronically, this is likely the car trying to warm itself up quickly. The jerking will occurs anytime you shift into gear at an RPM over a low idle as the torque converter is being engaged. If the high idle last more than a couple of minutes then you might have an issue.

Pathfinder "cuts out" at 2,300 rpm


Replace your MAF, its a little pricey around $280.00 or so but this will clear the code but make sure you have the ECM reprogrammed to perform a "learning" sequence since sometimes the code will not clear even though the vehicle will run like new. This reprogramming will most likely have to be a dealer performed procedure.

I am not familiar with this engine. But, if the alternator, PAS and AC are being driven by the same belt, then its possible that the belt is too slack, have you checked the belt tension ? That would be my first step. Hope that helps

Have a 2003 taurus with 3.o liter v6. At around 4200 rpm the engine starts to miss like it is a rev limiter. Am I right or is this another problem. Is smooth all the way to 4200 and then misses  ...


Yes it will act like it has a miss if the car is in park and you rev the car up, but if you are going down the road and hit 4200 rpm's it should not. Try checking the computer and see if it has any codes pending or hard codes in it.
