Hi, thank you for your assistance. We have tried what you suggested, but the problem still persists. We are in dire straights now. The exhaust isn't blocked. Pressure test was done , but nothing wrong. The throttle sensor was replaced. Please explain the converter you are mentioning. Thanking you in advance.

its the catlytic converter, but if you'ave already checked the exaust then it's not that. check your crank and cam sensors for resistance one of them may be bad and not setting a code.we have no information for these cars, but check for the kock sensor giving excessive retard and check iginiton system for proper operation. Also check the map sensor for proper operation. If that has a vacuum line going to it see if it's sucking together or soft. if it's soft then replace the vacuum line. and check the gasket around the map if it goes directly to the intake.

Hi hmac300. Could it be a relay in the fuse box that regulates the fuel supply.

the relay just turns the fule pump on and off. the fuel pressure is regulated by the fuel pressure regulator which is on the fuel rail. if you 've checked your pressure and its ok then that isn't it.
