I installed the rrm piggyback ecu, i wasnt happy with it, it made my car stall everytime it started it, so I took it out and sold it. but now my car still stalls, when it idles, any suggestions would help alot.

Thanks
Tom

 

did you reset the ECU?

 

Probably due to improper installation. Do you have a loose wire? How did you reattach the wires you had to cut?

 

I know i installed it right, I did reset the ecu, and i solderd all the wires when i installed it and when i took it out as well

 

Did you cover the exposed wire with electrical tape? The only reason I ask is because if the wires touch one another then you might have a potential problem.

Yeah i get the same problem too. It stalls out after I'm driving then put it in park. You can watch the RPM's go up and down and then it just shuts off.

 

yeah, thats the problem i have

 

You need a tune up. Buy new spark plugs some Sunoco Ultra 94 Octane gas. Oil change, Injector cleaner, change your air filter and then see if it still does it. You porblaby had an initial problem when you hooked it up causing your car to run rich and then fouwling up your plugs. When you pull them out look at the white part (ceramic) has the colour changed to brown? If so your plugs are shot.

 

Running rich will make you eat alot of gas right?

 

I had that same problem last week. Every time I turned it on the idle would be in the range of 1,100, then slowly go down and strat to stutter around 600, then die off. It's all better now! I found out that i needed to clean my fuel system VERY VERY good. I went to NAPA and my boy and I went in on the Lucas Complete Fuel System Cleaning Kit, which was in the range of $230, but it can be used like 8 time or something. I did that and it seems like it may have been my injectors spitting fuel instead if spraying it at an idle, which caused the engine to overload with air and bog out and stall. You dont have to go out and spend that kind of money, but I do highly recomend either using Lucas, Royal Purple, or Valvoline Synthetic products.

 

thanks guys
