I am having problems with my 954. I left it sitting all winter and now want to enjoy the nice weather. Battery was dead so i tried to jump start it and it starts after lots of cranking on the starter but runs like garbage. Anytime you give it any gas it boggs down and dies. and if u let it idle it will die with in a couple of min. after reading on this forum i thought i have a faulty TPS senor or FPR. I replaced the whole throttle body set including injectors, FPR and TPS and vaccum lines etc.(i bought them used). I checked and cleaned the plugs. and still having the same problem. I have the airbox still off trying to troubleshoot it. Whats next to replace or test? Any input would appreciated!!
