Ok guys heres the deal. For some reason my car is flooding bad. i can go down the highway at a dead 70 mph and it sputters. I can watch flood smoke barely come out. if i lay into it poof the magic dragon damn look at the smoke. When i'm in town it sputters real bad. But if i lay into it poof and it clears up and hauls a$$. Complete tuneup new tps, iac, maf, maf relays fuel relay, wires plugs, accells super coil, timing set to factory specs. Today i turned on the switch fuel pump ran longer than normal like twice as long. ANd i almost killed the battery trying to get it to start.

THen sometimes i bump the switch and presto fires up like a dream. Please someone help me out here. I was told these injectors flow more. And the other thing that gets me is i have a 1500 rpm idle. I know i have a drivers side exhaust manifold leak but it's been like that for about a month. I just havn't had time to fix it. I thought it was bad gas so i run it down to a 1/4 of a tank filled it up with premium and added fuel injector cleaner. Still didn't help. Now i did clean my enging and enging bay sunday morning with castrol super clean. I left the car running and it spit and cut off one time. But it fired right up. I didn't wet the distributor.

Pleas any help is appreciated. I'm totally lost.

 

come on someone please help me out. I"m practically begging here.

 

come on i'm dying here.. I'm missing work today because of this piece.

 

Anyone. Man i'm willing to try anything right now.

 

i am having the same problem i was told by a couple of mechs that it is the cold start valve
i don,t have the time to fix mine working to much but they said it is not a hard job and the new valve is relitivly cheap under a hundred bucks good luck and i hope this info corrects your problem

 

I am going to assume that you haven't changed your chip to accomodate the fact that the SVO injectors flow more than the stock 19 lb/hr...they actually act like 21 lb/hr (or so) and the problem is that your computer still thinks the 19 lb/hr injectors are in there. All SVO injectors are underrated cause there rating is at 37 psi and the GM/Accel injectors are rated at 43-44 psi.

Do a search in the TPI boards to confirm this. Your solution? Change injectors or burn a new chip to correct it. Good luck.

 

It didn't start doing it when i first put the injectors in. It started like 2 weeks later.

 

It may be that running that rich killed your O2 sensor. That still doesn't change the fact that your ECM thinks you are running a smaller injector than you actually are...thus causing it to mechanically run rich. I know the ECM can compensate only so far...doesn't your mileage suck?

Also, your cold start injector could be too blame...so just unplug it. It is a seperate system from the ECM anyway.

 

I forgot...also, your ECM could be bad, but it sounds like the ECM just can't control the amount of fuel...I still think that you need to change the injector constant in your chip and replace your O2 sensor...then see what happens.

 

If you can stand the down time send your injectors to Rich at cruzin performance. He does a set for $80 plus $10 for the cold start and has 48hr turn around. Allow 2days out and back for about $13-$16 each way.

I just got mine back; he said some were dripping so I think he cured my warm start issue.

You could unplug the cold start pipe at the fuel rail and plug it for a test.

If you think it's too much fuel cut back on the fuel pressure.

To see if the ECM is going closed loop, jumper ALDL A&B and start the engine. The SES blink rate should slow to 1Hz in a minute or so and the On/Off duration should be equal. If more On then it's running rich. If it doesn't slow down, you're not going closed loop.
