Sidom Veteran / Moderator Jan 21, 2010, 11:51 AM Post #4 of 4 (1407 views) Re: misfire no start sometimes Sign In It depends on what kind of tools you have as to what tests you can run. Without the proper tools to confirm a failure anything is going to be a guess. This is an OBD I system so to even look at a data stream is going to take a rather expensive scan tool as compared to some of the lower end OBD II readers now available. You said you're on a low budget & I can relate to that but if you can afford it and there is maintenance things that you've been put off as far as "tune up" stuff, now would be a good time to do them. Off the top of my head the 2 most common things I've seen on those for this type of problem are bad crankshaft position sensors, PCMs & related connecters. You can try gently wiggling the connecter that goes into the pcm while the engine is running to see if that has any effect on how it runs.. If there is any way you can get the codes read on this, it may be helpful in leading you to the problem area... A fuel pressure reading would be good as well.. If you have a spark tester, that would help let you know the strength of the coil.. etc......   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
