I got a 92 sc300 and the prob is cyl.5 is dumping to much fuel. I asked around and people said it could be as simple as a vac leak to a messed up ECU. Please, Any help is very much appreciated. Thanks in advance!

 

welcome to Cl.

1st- we have an engine forum, where this is being moved to.

2nd- "help" doesn't do anything for you, you have to title your thread correctly for the proper help to arrive.

3rd- you're gonna need to put up a bit more info, that is very vague.

 

Not to sure about the prob . Just got the car on Fri. IThe previuos owner jus said that its dumoing a whole lot of fuel in one cyl. Thanks for the advice. I'll post up when i find out a little more info on the prob.

 

Welcome !

As with most engine problems in our newer fuel injected engines, you will need to put in on an analysis machine to eliminate the guesswork..

A bad injector, questionable engine ECM, leaking valve seat to name a few of the causes.

I feel your previous owner did not have a clue...

 

Yes, and niether do I. Thanks Tammy!
