I get electrical gremlins occassionaly, and it's the hardest thing for me to diagnose. I keep throwing a TPS sensor low voltage, and occassionaly a MAF sensor low voltage. I think they are both related somehow. When the TPS problem happens, my shifting gets very erratic. With the MAF one, the car will cut out. Both problems come up the most during cold or damp mornings, and usually will go away after a good warm-up. It has to be a short, but I can't find it. I originally pulled off my TPSE (no help), replaced the MAF and TPS connectors (no help), replaced the TPS (no help). I have a Casper's volt booster (it hooks to the TPS), and that's coming off next, but talking to Justin at Casper's..says the TPS just feeds through the unit, and shouldn't be causing it. It's been happening for a few months now, but getting worse since the weather's getting colder. Anybody have some other ideas on this?
