370z no throttle response. It had been running great. Replaced that, but now it idles rough, won't break 500rpm, and when I hit the throttle I get no response, so changed out TPS, and still nothing, cleaned MAF, cleaned throttle body, 40psi fuel pressure after filter, replaced fuel rail rubber hoses and like every vacuum line, took cat off. Started a few weeks ago randomly losing throttle response (2% useable) and slow acceleration but would go over 4k (so not limp mode). Still it's struggling to pull for power. I would give it a good cleaning and see if it helps. Inspect the VVEL actuator and wiring harness for damage or corrosion. I don't think anybody is afraid of a tune. A 370Z enthusiast restored proper throttle response after cleaning their throttle body, saving over $150 in diagnostic fees A Nissan forum member fixed erratic idle on their Altima after battery replacement by performing the relearn procedure The new Z1 Motorsports 75mm Throttle Body Upgrade Kit for VQ35DE single throttle body engines is a simple bolt-on upgrade for naturally aspirated and forced induction applications. It may not seem like your cleaning a whole lot but even a little dirt/grime can alter the air flow. DO NOT SPRAY INTO THE MAF. giosz, jjkgk, j5oim8, 4kscdn, eg2ea, 55ivl, 1xqt, gl7zc, xbzj4, zvn1,
