ok fellas... here is my issues.. for the past 3 months i have been working on my 88GXL.. it blew its motor due to chunking the cat and wedging sideways in my Y pipe.. over back pressure.. also i was quite mean to it... i put in a new motor and it sucked... so i put another one in. i removed emissions and 5th and 6th port and air pump. installed a racing beat header and exhaust. hooked up everything right.. new plugs wires and everything.. the car runs like ***.. i have gone through every sensor to check for impedence.. replaced fuel pump and filter.. new lines new everything, tried 2 different ecu 2 different maf and 2 different CAS, i started to put all the stock stuff back and no dice. still runs like crap.. the timing is everywhere ive gone over the ignition harness and engine harness.. had my injectors tested and cleaned. used different FPR's ive got good fuel.. good spark, no vac leaks.. i thought for the longest time that was my problem.. but i had all the surfaceds flat filed and did new gaskets with great sealer.. all caps are correct and everything is routed as it should be.. im no rookie when it comes to cars... rotarys are fairly new to me though, ive matched up all numbers on my ecus and MAF and everything im using all the 88 stuff.. so no cross matching here.. the car wont make any power.. i have AWESOME compression. anyone have any ideas? i finally found how to make a code reader for a series 4 and am gonna check codes... anyone have any ideas??? please respond or if you have some time please call me 541 517 7660 im in eugene oregon and if any of you are near here i would pay you to come check it out if you can solve my problem..

that can do it right there man, if that sensor is bad it can mess everything up

sinisterddg

ok i changed the one on the dynamic chamber.. im not sure if its the bad one from the MAF there are two and i cant find a specific.. boost sensor did nothing.. now the only code i got is O2 but it will run fine without it even plugged it just stops feedback.. this is crazy i hate it...

andrew lohaus

you did clear out the plug in the exhaust right? maybe something got back into the mufflers.
