You need to check the fuel pressure under load. Since the tank was run dry
it is possible the fuel pump is damaged. Next would be to use the O2 sensor
to test the mixture. Excessive rich can also give similar symptoms. Fuel
starvation is also usually accompanied by back fires through the intake
manifold.

Subject: Re: 1985 1.9 Hesitation at higher RPM (kind of long)

Sorry if this appears twice - the list sent me a message saying that this
message didn't get through for some reason:

Thank you all for your replies.

1. David - Yes I should have thought of replacing the fuel filter at the
same time - kinda narrow minded on my part - I got wrapped up in the tank
replacement and didn't think.

2. Richard - that is exactly one of the problems I was having before but on
the passenger side. I inspected the driver's side and it looked OK - maybe
I'll apply some sort of sealant around there to be sure.

3. Mark - thanks I will check that test out in the Bentley

4. Neil - we've talked but again thank you for your replies as well.

Work has kept me busy and I didn't have a chance to look into it last night.
I did throw a bottle of heat into the tank to see if that might help but it
did not. On the way to work I still couldn't get past 50mph. Seems to Dog
out a bit lower than I thought - between 22k rpm and 30k rpm. If I give it
more than 1/4 - 1/2 accelerator she'll bog right down.

Thank you all again I will look at all of your suggestions.
