hello everyone this is my first post, even though I been reading the forum for a while. the problem that I have is that I cannot get my car to get over 180 kmph,I usually don t drive at that speed, but the car should be able to get over it without problem. from 160 to 180 it acelerates slow
the car stalled during aceleration, so I changed the fuel pump and the problem solved, the tps sensor is new, fuel pressure regulator new too the o2 sensor is a couple of thousand miles old too, so is the fuel filter and air filter, the spark plugs and cables are also new, the thersmostat and coolant temp sensor is new too.does any one have any ide what could be, only one time it went over 180kph., tires are also new.
the car does not have a cat. the screw in the afm was played around with could that be the problem, any ideas? the car is 60k miles,
the only thing unchecked is the fuel return line, could be clogged? any ideas?

Hi Andres, Welcome to the forum and congratulations on your first post! I agree you should easily be able to run 160 KPH (110 MPH). What happens when you approach 160 and what engine does your car have? I'd pull off the distributor cap and make sure all the contacts are clean, unless you know they are new.

I've seen nearly 260 KPH a few times in the 'S' so I know it is possible but that was long ago!

Surely Steve and some other guys will know what you should do!

hello steve I have the afm(aluminum box with square cover and the flapper inside) it has two part numbers 0280202202 and 0280202210, the mechanic that touched the car before moved the screw in it. could that be the problem? is there a way to put ir to factory values(the car does not have a cat) perhaps measuring the pins and moving the flap????

Adjustment screw is just for idle air passage so should not affect wide open throttle.

Have you checked throttle cable and accelerator pedal down stop in floor carpet to be sure throttle body butterfly is opening all the way?

I guess either 202 210 or 213 should work on your 164

The AFM installed 0280202202 and 0280202210 numbers do not match above cross reference chart? But match Alfa number 60513336

Hi Andres,I confirm this. I had Alfa 75 TS. A year after its purchase I did repair the engine. Maximum speed was 220 km / h. Between 150 and 170 acceleration is slow. Then the car as it woke up. But to 200. In order to be "squeezed" out of it 20 more I had to replace VVT, power steering pump, steering rack, do wheel alignment, change the fuel injectors, remove the catalyst and put the tires with less resistance. I have not changed only AFM. 220 km / h, it was the speed limit. But 75 is less than 164, and the size and weight.
This engine without any problem living 200,000 km. Then increased oil consumption. At this stage it is sufficient to change the piston rings, all seals, gaskets, connecting rod and main bearings and chains. Once again, the engine will live another 200 000 km. Check for yourself.
Gasoline with an octane rating of 95, oil Shell Helix HX7 10W40.

212km is factory top speed. How many miles on the motor?
I will repeat what I wrote above: Have you checked throttle cable and accelerator pedal down stop in floor carpet to be sure throttle body butterfly is opening all the way?
the engine 100 thousand kilometers roughly 60 thousand miles, running on 95 octane unleaded gas.
I have found on the manual two checks for the throttle.
one for the pedal, this model does not have a floor stop, and when you press the gas pedal the butterfly stops on the housing, according to the manual should have a 1 or 2 mm gap between throttle valve and relative stop. I guess the problem might be a tps regulation. do you know for sure what resistance values should have fully open? when you install it, it only fits in one way and there is no way of adjustment for it, right?

So, When you press the pedal all the way to the floor, is the throttle plate perfectly horizontal (wide open)?

I've been looking at this with interest - same basic setup tho older. I'd first ascertain if the car will run to redline and against the rev limiter in lower gears, mainly 3 and 4. If so, I would assume the motor to be winding out as it were. At this point I'd be looking at other issues and am curious are you checking speed with a GPS or on the dash. My dash is woefully inaccurate at high speeds. And above 160kph, very slow to go more. Reminds me of a boat test I saw once where the biggest issue was it wouldn't come on plane. They'd left it hooked to the trailer! Discovered it when they sent someone over the side to inspect for issues! Ciao jc
