hi, i just purchased a 91 240 and i need some help. i bought it non running. they guy said it just stopped running and he tried changing the distibutor. i figured he did something wrong and messed up timing but i checked it manually and seems to be okay. i changed plugs and wires and it sounded a little better when cranking it. then i noticed that the guage said there was no gas, put gas in and crossed my fingers, but i didnt get that lucky. it started but would die, i would have to keep my foot on the pedal to keep it running. but theres a LOUD tapping coming from under valve cover, so im guessing something with the valves is wrong. when i rev it, the tapping gets way louder and faster. and it also wont rev past 3.5k also i checked the new plugs and it was completely black and alot of gas on it, im also guesing im running hella rich. then i changed my oil and it seemed to barely stay alive w/o keeping my foot on the gas. still wouldnt rev past 3.5k what should i do? how do i get my car not to run so rich? and what do i do about the tapping? sorry for the long descrption but i just wana get my "new" car running.

the fuel is controlled electronically. so as long as the injectors are stock size, it really shouldn't be running rich. Unless, somehow the maps were reprogrammed?? That would prob require a standalone ECU. If you're hearing a tapping from under the valve cover, something is prob fucked pretty good. Could be a lengthened piston from overrevving. My advice would be to pick up a cheap ka24 off of someone who just swapped in an sr20. the kas are dirt cheap. good luck.

If the car isnt revving above 3.5k it's because your MAF sensor is unplugged, disconnected, or gone bad. Thisr would also be the reason you are running rich.
