Are you assuming its running lean or have you tested it?

by **96bzg** » Fri Mar 19, 2010 6:15 pm

tested dianostics and that came up it was running lean and machinic said it was also they are guna put fuel reg on it to check fuel pump tomorow

Have you checked the condition of the fuel injectors?

Why are you driving it in such low revs? Blacktops run best 5-8k :wink:

car is at the machinics is going to ring me on monday...

hahaha yea but you gota go past 3 to get to 5 and makes it a nitemare to get there and dodge as to drive pulling out of intersections and it starts splutering as other car gets closer !

Have read that some one fixed it by checking and replacing a few caps in the ecu? Mine bogs a little, but no spluttering.

yup, just fixed my silvertop by changing ecu

by **96bzg** » Mon Mar 22, 2010 2:26 pm

hmm may try to get second hand ecu and see if that makes a difference any idea price for one ?

funy guy ae mark ... well fuel pump is fine now reakons its injectors or ecu ... have sourced a ecu to borrow to check this

common problem on silvertops (and ae101 4agze) is that the capacitors tend to melt in the ecu. In your example those are the exact symptoms I experienced before replacing caps in a silvertop. Basically it messes with itself. You may get codes coming up but they could mean sweet f all as the computer is confused.

In 4agze they tend to jump into limp mode when this happens. Supercharger turns off, cant rev past 4g.

preaty gutard they didnt even work on car yesterday to try ecu or injectors. it only seems to run crap round 2500- 4000 then its ok im hoping it is ecu then prob upgrade to microsquirt one n get it tuned

ok in the weekend did work on the car replaced fuel pump swapd injectors spark plugs knock sensor tps and adjustd cleand throtle bodies swapd coil dizy cap and rotor leads checkd earths and oxy still stuters / misses goes beter tho ......
