I just bought a 92 Tracker, Man Trans, 2WD with a bad hesitation & poor idle when engine is warm. If I shut the ignition on & off, the problem clears itself momentarily. What did you do to fix your problem?

if your problem is the engine seems to run on 3 cyl instead of 4 then check the rotor and cap plug wires and the plugs and compression
cap =worn contact
plug wire =worn or broken inside casing
plugs =one bad plug
compression = one dead cylinder no/low compression

Or it could be a bad pick up coil in the distributor, some auto parts stores will check this for you. :2cents:

Here I am - answering my own post. Hopefully this may help some others. I had sent out my ECM to that guy on eBay (Steve George) who checked it out, said there was nothing wrong with it, and sent it back to me - at NO charge. He even paid for the return shipping!

Anyway since I could now rule out the ECM, I tried a new new filter. Not much improvement (maybe a little - maybe it was in my mind) I figured the problem must be in the tank - either the electric pump or the strainer.

I finally got around to dropping the tank today and to check the strainer at the pickup end of the fuel pump. It was very plugged with rust and looked sorta sucked in. I could blow through it but there was some resistance (there should be none). The Chevy dealer told me that the strainer was part of the fuel pump and wanted to sell me one for over $717 - I told him "That's what the truck cost me - I'll get back to you on that".:screwy: So I called the Suzuki dealer and also told me the strainer was part of the fuel pump, but his was only $275. I went to AutoZone and they had a strainer in stock for 15 bucks. I put it on, added fresh gas and a bottle of dry gas (lots of rust in there). That fixed it! It runs great now! I'm one happy camper tonite!
