running poor

I agree with Latech on this one. Run a heavy dose of Seafoam through it. It is sounding more and more like a injector issue. It could cause RPM surging and also a popping in the exhaust

I dumped a bottle of seafoam. I also only put in a 1/4 of tank of gas . I am not sure how many seafoam bottles/cans I can put in at once. I also double checked the plugs that I put in. And I did notice that they are copper plugs. I bought new ones again. But this time I made sure they are Platinum AcDelco plugs .

1 can of Seafoam for that 1/4 tank. Replace your plugs then start it up and run it. Alter RPMs a bit to cycle the Seafoam through the system. It really does work to clean out injectors. Hopefully that will clean it out good. Dont be afraid to run it around the block a few times and hit WOT (wide open throttle). If that doesn't do it I'm afraid you'll have to start pulling injectors out. They could've gotten gummed up from sitting for a bit. You know these high quality fuels they sell now...LOL

It is za 96.

Pull data stream from the obd port.

for 10 on ebay you can get a slick Bluetooth interface obd device. Comes with software for pc/phone/mac. Scanmaster on PC will work nicely.

If your pc doesn't have Bluetooth usb adapter, att and datalink both are running promotions to get free usb Bluetooth. Bluetooth is not wifi.





You will see whats going on.

Bucking, I can think ofa bunch of guesses.

Never mind I found it on ebay. I have a code reader. That I bought from auto zone. But that don't pin point what's wrong with it. When there is no codes to read. Lol

It is a Bluetooth obd/elm327 interface. Search Bluetooth obd. I have connected with all kinds of devices . If your online, you know how to setup a new connection. The only OS that I had trouble with is Linux.

With a laptop or nearby pc scanmaster will pull data stream, live sensor value /actuator status , code scan, performance data, 0-60 1/4 mile off the vss, etc. Fun stuff is the maps and graphs. If you know what should be happening you can diagnose at a glance. Check off bunches of suspects, when diagnosing faults.

Torque is good too.

Live timing , af ratio, fuel psi, iat, map, etc.

Do they make a scan tool or something? That will tell you exactly what's wrong with it. Instead of a guessing game.

It does more than pull codes.

Data logging for $10. I would have paid $10 to use it as a universal gauge set. The live timing is nice too. When I found out it could check the AC system high side and low side pressure, that made me believe I got my moneys worth.

Hey Spinn,

I've got one of those exact units. It came with some software that was free on-line anyway. What software are you using? The free stuff leaves quite a bit on the table as far as information goes, but it seems the really good stuff is pretty expensive.

Scanmaster pc, torque for my phone.

You need to be specific. It shows what's going on at the ecm perspective.
