I posting this up for a freind whos a member that doesnt have the time to post up here goes...
we replaced the blown head gasket on his 89 after he got back from moab it apparently let go somewhere out on the trail and he got it back home but soon after found the blown head gasket problem, also updated the brakes to a dual diaphram booster and new prop valve and in addition to that did the cooling system swap from open to closed or whichever way it goes..
Got it running tonight no air cleaner assy its going to have a k&n fipk adapted to fit the renix via a machined adapter, it also has no coolant temp sensor as it doesnt fit in the spot in the thermostat housing( its a huge metric thread vs a smaller american size)... the real problem is we cant get it to drive right after about 30% gas it wants to stumble and miss and backfire into the intake now we did correctly measure and adjust the tps for his 89 year using info from here(good stuff) his a and d measurements are 4.67 volts so using the 82% we set his b and d measurement to 3.82 and its not running right still??? WTF Any help with the renix gurus oh I almost forgot it has new fomoco 19lb injectors, along with pacesetter headers and a new 60mm throttlebody(renix of course)...
need some help here?? he did have to cut the o2 sensor wires to lengthen them with the new headers they were too short to reach the bung in the headers along with modding the hell out of the egr pipe to get it to fit...It seems to idle just a bit low and hesitates and stumbles a little after you pop the throttle sitting there and if ya pop it hard enough itll backfire for you... My thoughts are hes got a idle air control motor going( its still pulls just as much air with the throttle open as it does at idle) and it acts like a tps is going as well though all the measurements are good...
