Audi A4 2.4 Auto. Driving between 1000 and 2000rmp it feels like the gears are slipping, but also the revs just blip up a notch and down again, but above 2000rmp no problem at all changing gears and


The problem is in the transmission . Run the fault codes to check for faulty TCM or servo's and solenoids. Have a pressure test done on the transmission to check for internal leaks. Remove the pan and check filter condition and while the pan is off have the bands and clutch pack adjustment checked

It sounds like your transmission is slipping. Check your fluid levels, if they're ok, then take it to a transmission shop and have them diagnose it. Could be anything from a linkage to a rebuild.

Audi a4 1.8t random miss fire


Check out the AboutAutomobile.com site for NHTSA complaints. I believe there was a defect in the cylinder heads for this engine. The redesigned heads have a different suffix letter than the stock heads.

For a time, the Manufactuer was paying for the repair.

My 2001 chevy blazer is misfiring and will not rev beyond 2000rpm without cutting out but it idles alright


trying to rev the engine in neutral will not work. the computer will limit the rpms.it is kind of a goofy safety measure built into the system. to diagnos the missfire you can remove one plug wire at a time with an insulated pliers.the missfireing one will -not-slow down the engine speed. if all cylinder are firing properly at idle and only misfires under load you will probably need some help have a driver put on the brake and accelerate a little untill it misses. when you have verifyed this try the same thing with the plug wires while it is missing. do not keep the engine torqed this way for more thn a couple of seconds. you could damage the trans.. when you locate the missing cylinder you will need to find out why it is missing. look at the spark plug,and maybe swap one plug wire for another to see if the missfire moves to another cylinder. i am assuming you have no test equipment. if that does not change,see if you can get at that injector for that cylinder and lightly tap on it with a metal punch.if problem seems to go away or engine misses when tapping injector it will need to be replaced.

05 Impala missfire code 301 have changed


check intake for vaccum leaks,the gasket also and egr valve, thats alot of parts to have replaced without diagnosing first, if there are no fuel leaks and you said all injectors were replaced then you have a defective fuel pump, also these engines had misfire problem because of dirty injector but you replaced them so count that out. good luck.
