Sir
Before 2 months I changed my fuel pump
And today I checked the pressure is normal

Before cleaning IAC and throttle body the car was working good with only little bit hesitating

Scan for codes as well and check for a vacuum leak it may need a new iac was throttle plate cleaned on both sides or just one, if not clean on both sides. What is fuel pressure? Not normal or ok what is psi reading?
