OK guys, here's a good one for ya. My idiotic 89 hf (the car is all stock with 320,000) just decided to start sputtering, running rough, and refuses to idle. I am totally clueless. I checked all the common stuff I could think of from spark to timing. THE DAMN THING PURRED LIKE A KITTEN THE LAST TIME I DROVE IT!!! I let the car sit for 6 months, went to get it out of storage and ended up towing her home. All i know for sure is that now it's loud, runs like it's on 3 cyl, and even with my foot all the way in it (in neutral) it won't rev up past 3500. any guess as to what happened?

 

check for codes and see what pops up
