fk mudguts must be costing u a fortune sending it to all those different shops
anyway did u know some 1uzs have a 4000 rpm rev limit when in park and neutral
but ok in drive
so does your car have a 4000 rev limit when driving it
i had a similar problem on an sc400 right after the customer changed the motor
so im not sure what might have gone wrong
i changed maf and ecu and checked over afew other things but an hour later still coul dnot fix it and since customer was not going to spend money i said take yr heap of shit
and shive it up yr asss heheheheeheh
problems like this can take months to solve
but u havnt tried an ecu so far
can u borrow one of another car
unplug the maf and see if it does the same thing
the problem is its very very hard to tell if a maf is faulty just by reading the data on the scanner
i garantee 99% of mechanics will not know what the specs should be when driving in different loads so most of use have to sometimes guess what the problem is
when people say go thru it logically tell them u come and fix my fking car and see what they say
sometimes u go thru all the basics and get nowhere
goto a local car yard and ask to road test a similar car to yours
quickly drive it round corner to where your car is and swap over afew parts and test
u really need to just test the engine ecu and the maf
hopefully yr car doesnt have security
Hi sideshow, thanks for the advice.
The following things have been done:
Exhaust & Catalytic Converters checked
Valve timing checked
EGR valve cleaned & checked
Throttle Body & Plenum Chamber cleaned
Distributor Caps, Rotor Arms & HT Leads replaced (Old Spark plugs were not suspect so replaced after new ones tried)
Engine sensor connections checked
If you build up the revs gently it seems to get to the redline now and blipping the throttle achieves the same but (and here is the symptom that hopefully will enlighten someone): If you floor the throttle the revs immediately drop to 4000 RPM for as long as you hold your foot to the floor. If you then release it the revs will rise right up again.
Also if you play about with the throttle the engine sort of surges...
I have located a local racing ECU remap specialists for the 1UZ-FE so when I get a chance it will be going to them.
In answer to your question its the same in N or P or D.
I'll try disconnecting the MAF tomorrow.
Will keep you posted.
