1988 Toyota Supra Repair Question
- at 2000 rpm, the throttle cannot stay steady and goes between idle and 2000 rpm. have replaced air manifold meter and all hoses.
Have taken to four mechanics in the (DC) area, none have been able to figure it out. \ I just want to enjoy the car as I have for almost 24 years.
Carbuerator or EFI fuel system?
electronic fuel injection
Clean and test the idle air control valve , EGR and PCV valves-also test the MAF and TPS sensor-to include a fuel pressure/vacuum leak-check-start here
Thank you. I had thought something like this, but had no idea where to start. You've given me some starting points and I really appreciate it.
Please notify your web site that I could not get a donation to go through. I was using a credit card (not pay pal) and it kept telling me I had not input the: expiration date of card and type of card. I tried four times. Each time making sure it was on the form and correct, but after submitting, it's like the form reset those fields. I will still make the donation, just need a fix to this.
Does this model have a water heated throttle body?

Truthfully, I'm sure what a water heated throttle body is, so I will say no. This is a 1988; maybe the 90's versions had it.
Have you checked what I've suggested?
No, it's winter here and my garage is not heated and I'm in the middle of renovating my kitchen. It will probably be two to four weeks before I can get through everything.
