i have a 86 non turbo .....when i accellerate fast the car will sputter and hesitate at the 3 4 and 5 rpms and the gauge goes crazy and shuts down to zero and wont cut back on up to the 1 rpm when i shut the car off and turn back on. but the car will still run good when i accelerate slow. What is the cause of the hesitating and the sputtering ??

my latest installments is a new non turbo driveshaft and a new non turbo racing beat system

 

My friend had a mazda protege... no one in his family could drive it ...so the let me drive it one day I was getting on it... it did the same thing ur 7 is doin... gauge went to 0... this had a bad alternater... idk if it would be the same with a 7.. But all sysmtoms r the same

 

check your TPS connections make sure there is no corrosion, also make sure your 5th and 6th port actuators are working, doesn't sound like them but never know, i had a wierd accel problem once long ago and the TPS connectors were dirty, just scrape at them with a screw driver to clean them check all the connections in that area make sure they are all good, hell can't hurt to clean them all in the engine bay either...
