I would check to see if your injectors are spraying. Search for Accel injectors and you will find several tests you can run to make sure they are spraying. Accel has a bad rep of injectors crapping out and destroying motors cause they stop spraying fuel or don't spray enough.

 

I noticed this wasn't answered yet.. If your car is running lean it will run hot. The fuel actually cools the cylinders. I know this doesn't help you much but it's nice to know.

 

well i just ordered the racetronix injectors so ill change them and im going to change the opti to either a delteq or dynaspark dont know which one yet. any sugestions on which one is the better of the two let me know. and yea i did come to the conclusion about the lean fuel causing the over heating. i really do appreciate all the info and help. thanks alot guys........(oh and gals)

 

I would go Delteq, Dynaspark is nice but the voltage is still running through the opti which is the main cause of opti failure. Did you ever check the injectors or are you just swapping parts?

 

yea the injetors have been giving me problems from day one. i have already had two of the serviced by a injector shop here in houston and now i pulled the injectors yesterday to check them to see if they were leaking and three of the injector boots and o-rings are completely gone????? i was told they should have just burned up and out the exhaust. i dont know about that but im tired of dealing with these venom injectors there a nightmare!!!!!!! so i was going to buy the racetronix injectors in the first place but they were on backorder then and i was in a hurry so i ordered the venom and that bit me in the ***. so now i ordered the racetronix like i should have done in the first place. i have been running 2 of my stock injectors becouse 2 of the venoms have some issue with them now.( not sure what) you can hear them working but they cause a missfire on the cylinder. the stock ones in the same place it runs fine. so even if the injectors are not the hole problem they are for sure part of it in my opinion and i would rather just get away from them.

 

ok here is the deal. i took the car to a real mechanic and he fixed it for $250. it ended up being a bare wire shorting out on the frame. thats why it would come and go. i have driven it awhile now with no problems. he basiclly charged me for about 5 hours and a couple of small items. i love good mechanics !!!!!!!!! im just glad to have it back... i felt lost. lol well again to everybody thanks for your help and just wanted to let everybody know what the problem was.

thanks

I had a bad circuit problem with my 72# Seimens injectors. Bad solder joints. Leaned the left side when I was losing the 12vdc +. I tought it was a bad O2, but, I was losing the injector circuit 12vdc. Took me 2 weeks to solve. Since then, I have reviewed my ability to solder and wire. Sorry I was late to your post. (97SS 383 D1) B.

 

too bad i just saw this, i could of told you my car was doing this last month and my bud said to inspect all the wires at the red pos junction box and terminals on the battery. they were dirty so i shot electronic parts cleaner and cleaned and sandpapered all connecting surfaces with 600 grit till they were nice and shiny. put it all back and wouldn't ya know it's all good and running even stronger than before.

he said the battery wasn't getting enough juice to the system during running. i always thought the alternator took care of that but i was wrong, the battery power is also needed during running

 

hey guys just to let you know the wire that was bare was the water pump temp. sencor in the front of the water pump. someone at some time or another changed it out and when they put it back together they didnt even use butt connectors. they just twisted the wires together and put tape around them. god i love peoples mechanical abillities.........
