: sluggish 3.0

04-26-2011, 09:36 PM
hey guys. I recently bought a 1991 toyota pickup extra cab with the 3.0. It ran great for the first week or so then started having problems. It was reading 4 codes; knock sensor, egr system, air intake temp and running lean. I cleared the codes and now it is only reading two codes. Code 24(Intake air temp signal), and 31(Air flow meter circuit or Vacuum sensor signal fault). I need to get this problem resolved but not too sure where to start and would rather not take it to a mechanic. If anybody has some info it would be greatly appreciated. Thanks. geoff

I wish I could help you out. The only advice I can give you is to make sure to post this on the national forum as well. Either under Newbie Tech or Truck Tech. Good luck!

Gawdamn son...

You should have gone on the forum sooner... 3.0s are notorious for failing. How were you able to transfer ownership of this without doing an emissions test? It would have never passed emissions with all that going!
