Help - Pinging and TPS issue
'88 302 EFI AOD
Recently started expeiencing a pining and lack of performance around 1800-2200 RPM range.
Changed or did the following
Cleaned Throttle Body
AC Delco Rapid Fire Plugs
When I checked the TPS (old one), voltage was reading 4.8 all of the time, So I changed it. Well I replaced it and checked the voltage again and it still reads 4.8 [img]images/graemlins/confused.gif[/img]. Pulled the codes yesterday and with the new TPS I had a 63 code.
If I wanted to check the vacuum what is the best way to do so?
Any ideas on what else I can do concerning the pinging/lack of performance and what I might be doing wrong with the TPS would be appreciated.
