I have a early 93 viper that has been running rough. It starts pretty good on the second try hardly ever on the first. The car idles great revs up faily good when no load is on the car.
BUTTTTT then I get going down the road and get a load on it and it runs like hell. Almost as soon as I hit 4000 rpm it starts to sputter and back fire. You put the cluch in it goes back to normal. Normal as long as you keep the revs between 2700 and 4000 rpm.
Now I did install a new battery to try and solve this problem. I did the trick touching the + wire to ground then reseting the WOT. I also installed new plugs and one new plug wire that was cracked. I have the the other 9 just have not had a chance yet to install them.
The car has a full header pipe type exauhst. Looks to be a Corsa. Not real sure about what else. The guy I bought the car off of did not know a whole lot about it.
Oh and the car was running like crap before the battery and plugs so I don't think those are the problems. Is there a TPS on these cars? Both throttle cables look to be the same postion.
